hi gruppe,
ok my car is running really bad now...here's the lead up to it.
Thursday - i installed a supersprint resonator (eliminating the cat converter)
Car ran fine on thursday.
didnt drive the car on friday.
Today: was planning to install new engine and tranny mounts.
Drove the car from parking lot into my garage - car revved really freely...felt really good.
Managed to swap tranny mounts. Attempted motor mounts but bolts are too hard to reach and tight. I removed the AFM and when i was reinstalling it, i heard this funny sound coming from the front of the motor - like a buzzing sound. after a while it went off.
Drove the car from garage to parking lot - car felt really bad, lt starts fine, idles fine and is fine upto about 1500rpms. Above this and the car vibrates alot, i thought it was the mounts, but the engine sounds like its struggling. Either its flooding or fouling....like its on 5 cylinders.
BTW my car is a 87 325is.
So what could possibly be wrong with the car now?
This symptoms is similar to what happen to my E30M3 - a bad O2 sensor. Could this be it? I dunno if its ever been changed.
Looks like the part number for the O2 sensor is 11 78 1 716 which is the car specific Bosch part. There is also a universal 3 wire Bosch part that will work with my car for 1/3 the price of the original unit. Anyone used this before?
Thanks for your help.
