I have a 1990 Nissan Maxima and my car has been running very sluggish / rough idle for the past 2 weeks. It hesitates when I take off from a complete stop. I've changed the fuel filter, spark plugs (Bosch), and air filter. By the way, I took the car for a fuel injection service about 2 months ago.
I took the car in for a computer diagnostic and the computer did not pick up any problems. The mechanic told me that it might be the catalyic converter, I changed that and it didn't help. Now he tells me to change the O2 sensor, TPS, and idle control sensor. The parts are very expensive!!! I was wondering if anyone has experienced my problem or if anyone can give me some advice. I just noticed yesterday that the air coming out of the muffer is very hot and it is lightly sputtering. Sorry for my long message and I want to add that this web site is AWESOME.
Thanks,

Mr. G
