I'm having some problems with my 1995 sho mtx with 168k miles. I bought it back in the middle of July and the previous owner said that there was a recent minor leak from the back right of the engine. He was pretty meticulous about maintenance giving me old parts of the things he replaced but most of it was minor stuff besides the clutch and said that he did a front 60k at 120k. It ran fine for the most part for 2 1/2 months. The only problems during that time was that every few days when starting the car the rpms would be bounce around instead of steadily idling it would go away once I put it in gear and started driving. The other thing during that time was that sometimes under 4k rpms it would be slow to speed up under wot like it was being bagged down and the he oil leak wasn't bad until the couple of weeks before the first time it broke down and I used about 5 quarts to keep it topped up. When it broke down the first time I was on the highway in 3rd gear going to shift into 4th when the tach dropped down to 500rpms with the engine still running but had no power and then it started bucking and I had to put it back in gear so I could get over to the shoulder since I was in traffic and during that it was bucking pretty badly until it shut off completely. I opened the hood to see if there was anything immediate that I could notice that would have caused the breakdown I didn't see anything but I did smell some burnt coolant from the passenger side of the engine. I had it towed to the shop since I thought my coworker would be able to fix it and he replaced the fuel pump. After that though the sho still wasn't running right. Every time he scanned it on KOEO it would say code 11 and on KOER it would give code 548. It would either start up immediately or take a few tries to start it once it was running it would either be fine or misfiring out of the 2 cylinders on the passenger side of the engine bad enough that the car was bucking. When it was running fine it wouldn't have any power when driving it through the whole rpm band or it would gain some power after 4k rpm until the tach would drop out and the engine would be running like it was idling until you would do anything to car and then it would stall. When restarting after it stalled the car would take a while to restart to where it would backfire when finally starting to run or it wouldn't even crank. The other day my coworker when he was looking at it jiggled the connector at the top of the engine to the crank sensor and after that the sho ran fine for the weekend only twice where I drove it cold that it had the no power through the rpms and both times after jiggling the connector a little it would be running fine again. It broke down again on the way home from work yesterday where I was merging onto the highway and right after I finished merging the thermostat had opened up and then tach dropped out again, no power and it stalled once I turned the wheel with no power steering to pull onto the shoulder. I opened up the hood I could smell some burnt coolant and jiggling the connector didn't work and the sho wouldn't crank at all. So I had it towed back to work and I haven't been able to look at it since. I figured asking here would be a good way to get it running again.
