My 89 lesabre is still having engine problems. The MAF sensor is not the problem, i got a junk yard one put it in, its the same even if i unplug the sensor. There is ALOT of water coming out of the tailpipe also, the car idles around 5-600 rpm, sometimes it will stall, sometimes the engine light is on, sometimes its not on. Also u can tell that the car is running rich from the gas smell in the exhaust. Could it be a intake gasket leak? Or maybe it needs a whole tuneup with fuel filter, pcv, etc? Where should i check for possible vacuum leaks and how would i do that? Thanx 4 the help.

Try to get code read.

Check the computer code(*) with the procedure here: http://www.bonnevilleclub.com/forum/...e=article&k=57

You mention "still" running bad. Where is the original post?

We'll want to see what has already been suggested/tried.

500 rpm idle for your car is normal jamey. Have you checked codes then disconnected the battery for 20 minutes to clear the computer?

the water is probably from having a 17 year old exhaust. Don't catalytic converters change harmful exhaust fumes into moisture?

I have my lesabre running decently good. since were in the same town we could take a look at your car....check over the motor really well, I also know where theres another car we can get parts from for dirt-cheap compared to scrap.
