Hey all I got a 94 325is, the cars been idleing really rough, when iI go to accelerate the car just thumps and does not accelerate very much, occasionally it will get a boost of speed. As im cruiseing the car seems ok but when i switch gears, idle or accelerate it runs really bad.
I just replaces the o2 censor, the spark plugs appear to be ok (only about a year old), and the injectors were cleaned out about a year ago, just put some injector cleaner in it as well this week. The car is pretty much stock except for a Dinan sport chips almost 2years old and a cold air intake.
If anyone can lend me some advice I would really appreciate it!
things to check in no particular order... clogged catalytic converter, clogged fule filter, fuel pump, huge vacuum leak, bad coil. since you have an obd1 car, you can get the codes to read out from the check engine light to rule out a bad coil.... filter should be changed if it hasn't been done in recent memory, and cat can be rudimentarily checked by noting exhaust pressure....
start digging and let me know what you find and we can take the next step if need be
