Well so much for it running good. Took for few miles yesterday and it stalled out. drove home and it stalled another 4 times. each time it started up and ran fine for a bit. the last time i was watching the gauges and the RPM maxed out, then it stalled with an electrical fault message. Now it turns over but never starts. So i guess to start at the fuel and g from there. anyone seen this issue before?

during my search for the "vibration dampener" i found one on Ebay for a 1991 Reatta. It was called a "vibration dampener" but it was the harmonic balancer with a rubber ring mount on the back of it.

i am back, took the car to a local shop and they had it for a week. They said they had it running good and then it would go back to the "rough" state. They tapped on the ECM at one point and it went good again. So they replace the ECM and said it took care of the issue. I got i t home and let it get warm to see if it was good and stared stalling out. I put some new gas in it and drove it around the next day and it did not stall out. I am not completely believing it is good but i dont want to drive it too much with out the shock connected to the motor on the passenger side. I have been looking to replace it but not finding a new one. Anyone know if this is a "needed" item or where i can get a new one?

So i posted before about this Buick. Thus far i have changed out the Oxygen sensor, cam sensor, crank sensor, coil pack (twice), MAF sensor, and ECM. Background, i parked it at the airport for a couple days in August when it was really hot. It started hard, which was unusual, and has been messed ever since. It starts every time and runs, the battery is a POS, so that does not help. Meanwhile, it runs and does not give off any codes other than ones induced when i unplug things. As it runs the engine misses a little and the tac shows 6375 (the max it can display) about once every 25-30 seconds. the engine revs up and down like someone is purposely rev it up and down just a little. The tac thing sort of throws me, it shows that high rev but it does not sound like it is revving that high. I have run it with the MAF sensor pulled, with little change but there is change. With cam sensor or crack sensor unplugged it will not start. Remove the oxygen sensor and it will run about the same as it does with it connected and mounted correctly. Removing the oil cap and nothing changes. I removed the plug wires one at a lime as it ran with little change and spark at every plug of the coil pack. It does backfire but not very often. So i am trying to see if there is something else i missed. I am at the point of doing a motor swap but i want to be sure it is not an electrical issue, making a swap pointless. I suspect the timing jumped just enough to make it run, while it tries to correct itself. Thus the backfiring and funny revving?

i am going down that road. i pulled the oxygen sensor and started it, it ran as it usually does. then i put the sensor back in and it ran as it usually does. One other thing i was looking and found the RPM gauge has a 0-6375 limit. 6375 is the reading it jumps to every so often. the engine does not sound like it jumps that high. it is only for a second i see that value.

So i replaced, cam sensor, crank sensor, coil pack, ICM, and the MAF. Checked the voltage on the sensors and the pressure of the gas line. all are good but it is still running rough and the RPMs jumping up to 6000 for a second as it runs. Also the cad converter gets red hot do to the missing and back firing. So i am believing the the timing has jumped a tooth. anyone have another idea or is it time to tear out/repair the timing?
