Dealer promised to change all doors and roof gaskets, and after 3 years I had to order them for $600.
Some interior lights had to be replaced.
This year radiator started to lose coolant liquid making the engine to blow on warm days like a hot soup.
Brakes need to be checked.
Alternator does not work properly.
Same old story. You buy a used car from a 100 tooth smile dealer and seems it never ends surprising your wallet. After all it's an old one and who knows what had been changed or modified to make it look new.
But oh well, that's how it is with used bergains.
After all it's a great sport classic car still able to catch attentions from anywhere (expecially women) affordable with a reasonable price, even if those 80s low performance engines should be replaced with something new.
I think this is one of the slowest Corvettes because of the old Crossfire Injection (from 79 to 86 I guess) but still kicks ass!
The performance of the 1984 is really not even near as bad as the poor performers of the late 70`s. A simple way to get more power out of this animal is to get that catalytic converter off of there or replaced with something less restricitve. I now run no converter with Flowmaster mufflers and a few other goodies, but even just replacing the mufflers should give you enough horsepower to keep up with the Fuel injected versions no problem. 1984 is the only year they used crossfire on a C4 Corvette. Changing to fuel injection gives 25 more horsepower on thge 1985plus models. You should easilly be able to achieve that by changing the exhaust a bit while still being able to pass aircare no problem if your city requires that.
I am not being disrespectful of the first comment, but the cross-fire was used in 1982 and 1984 (no 1983s were made due to design problems for using a V8). To the review writer- the 1984 is the slowest of the C4s with only 205HP and 290 FT/LBS. My father raced me with his 1971 vette with 270HP+ (his is slightly tuned. My 1984 vette flew past him without a problem. By the way it is stock!
The 1984 was the first corvette to be called a super car. With it's 49/51 weight it handled better than any corvette before it and with the Z51 package you were sure to have one of the best handling cars in the world- even by today's standards.
If you are having problems or feel you Crossfire is slow or low on power, check out x-ram.com, these Vette's make more hp than tuned port's.
What can we GM 305ci and 350ci TBI owners do to get more HP?
My 1992 305ci and 1984 350ci produce around 200 HP.
Howa can we get 250 to 300 HP?
Making the engine to blow on hot days??? Bergeins??WTF!
No offense, but if I had a vette (or anycar for that matter) the first drop of anti-freeze I saw leaking from the radiator would have been taken care of ASAP, just driving around letting the car overheat (especially a small-block crammed into a tight ass heat absorbing compartment like the vettes) is just asking for problems.
Anyway, any car more than 5 years old is gonna have its share of problems, buying any car from a shady dealer (especially a corvette, something typically hammered on and thrashed before its traded in) is (no offense) a stupid thing to do.. these cars have always been high maintinence, the addition of fuel injection just made things even more complicated (the stock sensors are made to send off the check engine light at 60,000miles even if theres no prob) at some point your going to have to take it to a certified mechanic because tolerances on the engine are tight and any shortcut taken on do-it-yourself repairs will come back to haunt you... the cross-fire system is underrated, the old (true blue) z28 camaros of 69' used the same style setup on its 305 to pump out a insane amount of hp-per-liter (though the dealers kept that secret) theres a ton of mods that can be done aside from getting a x-ram manifold given that you have access to machining equipment, just look online and youll find a small following of cross-fire fans willing and able to give advice!!!
P.S. it's a sports car meant for the old or rich (or both) that might drive it once every other week, it wasnt really meant to be a long-miles daily driver, so high mileage vettes are a curse (a beautiful one at that) unless you're a experienced mechanic!
Does anyone have, or know where I can find an engine for my 84 corvette, the L83 350 crossfire, thanks.
I recently bought an '84 Targa; silver, crossfire injection...is that? I haven't driven. I traded it for a '65 C10 longbed. I'm bowtie. Anyhow, I'll let you people know what an '84 Targa is like...tomorrow!
I only came to this site to find if someone could help me understand why my sons 84 crossfire 350 dies out the way it does. It starts fine, idles out OK but then just dies to a stop.
It restarts OK only to repeat itself over again in the same way.we've replaced the magnet in the distributor, changed the electronic ig. module reset the timing reset the throttle bodiesin sink, new spark plugs/wires.not a starting problem. all I can think of is must be something in the computer, but I'm not sure. I don't have any way to analyze it.
I doubt it is computer related. I would suspect something with the fuel delivery system. If the problem was ignition related, it the symptoms would probably appear at all times.
IF (I do not know this for sure) the crossfire injection system is like GM's throttle body injection system, the vehicle does not have a fuel pressure regulator (but pulse width modulates the rate of fuel flow at the injectors) so that being the culprit is probably out.
I would rather suspect a problem with the fuel pump - e.g., perhaps it can generate enough pressure to prime the system enough to start the engine, but not maintain it enough to keep it running.
Does the engine sputter and die, or cut out all at once? If it sputters and dies, I would say it is all the more likely a fuel anomaly.
Another strong possibility is the fuel filter. Again, you might be able to push enough fuel through to prime the system, but a clogged filter is obstructing flow. Once the engine starts and the initial pressure from the prime disappears from the injectors opening, she stalls.
The fuel filter is a maintenance item anyway, so it will do you absolutely no harm to just go ahead and replace that without any further diagnosis and see if it solves the problem.
If it does not, I would look into the fuel pump.
My 84 Corvette occasionally (1 to 3 times per month) starts OK, but when I put it in gear, it dies out. I have to crank it several times and pump the gas to keep it running. After a minute or two it runs OK. Seems like it happens when the engine is cold. I also think it is a problem with the fuel pump, but haven't gotten around to replacing it yet.
I bought Corvette 1984 with cross fire engine, but I don't know if this car has fuel injection or not? I cannot make the engine running. Does this car have an electric fuel pump or manual?
But the engine runs with engine start spray.
My 1984 un-modified Corvette just started leaking gasoline from around the top of the tank... after I slowly drove over a huge "speed bump." Anybody else experience this? Know the cause or cure? I just read the recalls and saw there was a rear axle problem where new "retaining kits" had to be installed. Seems to have been some sort of flexing problem that caused this, as there are no "scrapes" in the undercarriage.
Any advice on how to access the top of the tank? Looks hard to drop the tank. Anyone know if removing the area around the filler cap accesses this area?
Try running half full only. I only burn 1 tank a month in mine to go to local shows etc. I had a boat, same issue, it expands out the vents and leaks. Filled less, no issues.
I only came to this site to find if someone could help me understand why my son's 84 Crossfire 350 dies out the way it does? It starts fine, idles out OK, but then just dies to a stop.
It restarts OK only to repeat itself over again in the same way. We've replaced the magnet in the distributor, changed the electronic module, reset the timing, reset the throttle bodies in sync, new spark plugs/wires, not a starting problem. All I can think of is must be something in the computer, but I'm not sure. I don't have any way to analyze it.
I had the same problem with my '84 Crossfire engine. It gradually got worse and then wouldn't start at all. Turned out to be fuel pump failure. If you're handy, you can replace it yourself. It will cost between $85 and $110 for the pump and about $18 for the pickup strainer. You might have to change to a upgraded wiring harness. If a shop does the work it's about $200 labor.
