I picked a nice '92 Z34 with a 5 speed in it, does anyone know how many of these were produced?

I'm the owner of a 93 (White) Z-34 and a 94 (Black) Z34. The black one is a parts car that was fudge packed and sent to the auction. It was a wet miserable auction outside and I only paid $350 For the black one. I have since swapped motors and am still trying to figure out the major bog at full-throttle. I pulled the motors out the top and had maybe 1/4 inch to spare on one side. In all I'm thinking it took @35 hours to do both, this was from a Thursday night to Sunday morning. I am my own mechanic. As for spark plugs I can do mine in 10 Minutes. No cutting! No doubt it's a pain in the, but to work on, but it's worth it to me.

I have the chance to pick up a 93 Lumina, with a 3.4, but it has a broken timing set. Does anyone know if it would bend the valves in this case?

I have a 93 z34, when I first got in it I completely fell in love with the car. I've had most the problems that everyone else has except the timing belt, but only had the car for a year. it great driving down the road having a little Honda come outta nowhere and then you step on it and you can't see it anymore. I had a major electrically problem just like someone else's, the car wouldn't start or it would die out after a few minutes, turned out simply just to be the positive battery cable, replace it and haven't had a problem since. Keep up the fun driving, I certainly will!!!

I have a 1993 z34 Lumina. I have had this car for about a year now, it has 186,000 miles on it. Haven't had any real problems with it except one. This car has got me baffled. I also am my own mechanic, there is not much that I cannot handle when it comes to cars. For some reason one day, the car would sputter and die at an idle, you would have to keep it running with the petal. Hooked a scanner to it, and the temp. sensor code came up. It was about 75 deg. that day, and the coolant was reading -45 deg. Simple fix, right? So I changed that out, and code still exists. Turns out this goofy 3.4 has two temp. sensors. An engine temp. sensor and a coolant temp. sensor. But they both feed in to water jackets. And they are both a real picnic to get to. So I changed both of those, and now the car just idles at 3,000 rpm. No problem. Idle air control code pops up, I have gone thru 3 of those, reset the code prob. 5 times, still no fix. If you shut the car off for 10 minutes, fire it up the car runs great. I would love to drive it into a tree, but my wife loves it. Any ideas?
Please e-mail me at: email@example.com this car doesn't have long to live...

I own a '93 Z-34 Chevy Lumina also, and I'm having the same problem as mentioned by another owner. The car quits running for no apparent reason and won't start, sometimes for days, and gives no problem codes or check engine light! I've been told that the problem could be a "crank position sensor" or the ignition control module. My car is still sitting today because of this problem. The local garage wants about $1000 to replace these items. You can probably do it yourself for much less. I'm going to replace the "crank sensor" first, then see what happens. I'll keep you posted... oh yeah!...I've had many of the problems mentioned by other owners here; eg. timing belt, alternator, ridiculously tight engine bay, and others, but I still like this car!

For the person with the lumina z34 idling at 3000 rpm, just brought a black 93 z34 with the same problem. Family works for chevrolet dealership and said to check intake gasket. Replaced intake gasket were oil was leaking and now car idles normal and purrs like a kitten. Hope this helps.

To Ken with the starting prob. Have you hooked it up to a fuel pressure tester?? My car was doing that... but I am my own mechanic, and I replaced the fuel pump... and it fired right up after that. I would say check your fuel pressure before you get into the sensors. Sometimes they just get week, but don't actually go out... I drove on mine for about 4 mo. before replacing it, so I would strongly recomend checking that first. And yes...$1000 is a crock, considering the part is a $20 part! If you do have to replace sensors... they are very easy... they just unplug and you plug the other one in. And any local parts store can print you a diagram of where the sensor is that you are looking for. Even if you're not a mechanic, I'm sure you can do it and save yourself lots of money!

To the Z34 owners with the high idle problems. I had the same thing happen to my 93. I would check all your vacuum lines, not just the rubber lines, but the plastic tubing also. I had a cracked plastic line that drove me nuts until I found it. I also had the same problem in my other Chevy, a broken plastic line that caused an idle problem.

I am having a problem replacing the timing belt on my 93 Chevy Lumina. I can't seem to get the bolt out of the pulley. Any suggestions?

I have a 1992 Lumina Z34 automatic that has problems shifting into 2nd and 3rd gear. Other owners of Z34s have suggested to change the shift solenoids. So before I do so I wanted to know if there is anyone who has replaced this before or is there anything else I should check before changing this. The Car starts and idles perfect. I found a Vacuum line that was broken and I fixed it which was located near the battery, I'm not sure if this could be the problem because I do not drive this car in the winter. Please email at firstname.lastname@example.org.

Hi, I recently purchased a white 93 z34 Lumina from the original owner, a 67y/o lady!!! Couldn't really understand why she would buy a car like this, but oh well.
The car has every option available that year with a red interior. It's a great car and everything I ever wanted, it seems to be great on gas if kept at 2000rpm or under, just driving around town, I read another post on here that said Lumina came from aluminum, does this mean the body is aluminum? When I looked at the car before buying it, it didn't have a speck of rust any where especially the floor (which is a big shock for any car around here older than a 95, considering I live in new Brunswick) but if the body's aluminum, this would explain why its in such good shape. it had all the maintenance regularly performed, and got everything it ever needed and had a lot of attention. I plan on taking perfect care of it as well. I read they have timing belt issues as well, would any one know what would be a good mileage to regularly change the belt? And possibly any other pieces that would need changing or attention?? Thanks for your time.
