I bought an 84 Corvette with 600 original miles. When I took it off the trailer, it started rough due to a weak battery, but then ran great. Had tons of power and seemed perfect. I then changed out the battery and the car would not run properly after. The car runs and sounds great in neutral, revs up, but when I put it in drive, it bogs down with no power. Anyone have any ideas?

The engine being weak in gear, but fine in neutral is a sign of it being in "limp home" mode. It's possible the battery change caused the ECM to malfunction. I would try disconnecting the battery, leaving it a while, then reconnecting. It may reset itself.

I have been noticing lately that when I'm driving my 1984 Crossfire injection C4 Corvette, that when I'm giving it gas while driving, it seems to act like it is cutting out on me and sometimes even stalls completely out when driving. Was driving it tonight, and it backfired and stalled out completely on me. And now it doesn't start, just tries to crank over, but it's not starting. Does anyone have any information that will help me get my car up and running? Thank you.

Fuel pump on a 1984, go where you add gas to the car. You have to remove the cover around the gas cap, then you can get to the fuel pump. You should be able to pull it right out. Just a few bolts hold it in place.

I put a 1984 C4 Crossfire motor in my 1987 R10 and it spits and sputters. How to fix it? I need help.

I don't make just any random LS swap comments. You have to evaluate the budget. Do not see it being practical. These cars can be picked up easily well under 10k. Add 7k to 10k for a finished quality swap. I would keep it stock or part out. Take the proceeds or start fresh with a nice used C5 with the new platform with LS1. Be careful on early ones as some had the LT1 or a LS1 from the factory.
I think there's a guy on here that likes to mock the bulletproof comment I made. Cool, that's great. But making a random comment may potentially be quite costly for a new guy entering with a new Corvette. You may just have bought one or inherited whatever. I do not feel this is a cost effective swap at all. I have 30 plus years of ownership on different gens. I still like the cars, but am up for a change. Hope my opinion carries some positive feedback for your specific year. If money isn't any factor, it can be done. Start adding up other things like paint etc. It could be applied to a newer gen. already set up. 365 HP plus on a C5 brings a lot more to the table. Plus better handling etc.

Mocking the bulletproof comment? I've seen it posted many times. In fact I've used it myself regarding the Ford modular 4.6 and the Buick 3800 series 1. Why? Because they both are. Now back to the Corvette on review.

The 1984-1988 Corvettes are by far the lowest-priced 'Vettes on the market. Base model C4 Corvettes are not generally considered collectible and it's doubtful they ever will be.
Essentially, a C4 from the '80s makes a good starting point for an enthusiast's ride, but it is a poor investment. I can buy these all day long at 4K easily. I am staying strictly on topic on Corvettes. If you want to do an LS conversion and kits are available, do your thing. We all have an opinion. Mine drive your 84 and keep it running without adding extra higher expense items. You may get your money back leaving it alone as is. Save for a 98 C5. It has the LS1. Why did I pass on a 97? Because I always wait for a second year of a model change. If there are any issues, they may crop up more than usual in the first year.
I am not talking Cadillacs on this review. Buy the C4 kit, and if that's your direction, fine. I always look at money and where it's well spent. I don't see it here. This is an emotional hobby, mainly driven by transporting you to from A to B with varying levels of fun involved. C4s are greatly affected by C5 total redesign and a complete world difference in gens. They don't cost much more. I have seen them as low as in the 12k range. But very high mileage. Getting into electronic issues and anything Vette, it adds up quick. If you own an 84, by all means drive it and have fun. Costly restorations and upgrades are only good if it's a car you plan on living with for a very long time. I have owned 2 Vettes at a time. Some guys like to comment; if you do, let us also know if it's just an observation or actual ownership. If any Corvette, then or now. It can really help out another owner or prospective one. Knowing someone that's really been there. You can buy an entry level Corvette and that's only the beginning. It's the repair and restoration that is your biggest cost of ownership. Hope I helped. We all work hard for our money. The other commenter wants you to do an LS. I would like to see his justifications why that is.

Did you read comment 01:59? He was referring to an '87 R 10 pick-up, not a C4 Vette.

I don't think he can drive it, seeing that the motor was swapped into the truck.

I have a 84 Crossfire and it starts great and idles great. Go about 25 MPH and it spits and sputters. Help please.

The value of the car does not really warrant a LS swap. Fix it if possible with the existing motor. I can't see doing this unless you inherited it or have a very deep personal attachment. These cars typically run only 3500-7k for a very low mileage turnkey example at 7. These are the lowest cost entry Corvettes, plentiful in much better, lower mileage condition vs entering into a engine swap. I also would not do this in just any Camaro. I've had both cars in various gens and am only offering a first hand constructive opinion. I did some similar situations more for experience rather than starting out building and restoring a rarer model. Learned body work and paint on a low cost example before stepping up to the same on a mid year.
