Engine Performance problem
1999 Isuzu Rodeo Question 6 cyl Four Wheel Drive Manual 150000 miles
hey 2 car pros-
This problem has been gradual. For a long time, my car would idle high. It would stall after long trips of 100+ miles. It would run fine around the city. However, after longer drives, when slowing to come to a stop, it would stall, even before I'd reach a complete stop. To trump this problem, I used to glide into stops and rev the engine to keep the RPMs up, almost as if to keep pressure or gas in the engine to avoid the stall.
About every 5th time that I start the car, it will idle higher than normal at first. The engine will almost rev, but this will eventually settle and the car will run normal after a few minutes.
Coming home yesterday, the engine stalled near my home. This morning it will start, but the car will stall almost immediately if I leave it in neutral.
In search of the problem I have replaced the Fuel Filter, IAC, MAF, and Cleaned the Throttle Body as best I could (however, I used IAC cleaner because I had it in the garage). I have also replaced the Fan clutch 6 mos ago.
I would like to get my car working again. And I'd love to fix this problem. Where do I go from here?
