I have 91 toy with a 22re, everytime I drive it, once the engine gets warm it gets a low rough idle and stalls when I come to stop. A couple times it stalled on me mid turn after taking my foot off the pedal. I just put a brand new alternator I did an egr/air injection delete. I have no vacuum leaks. I sprayed the vacuum ports with brake cleaner and I did a smoke check. Still zero leaks. Also my gas mileage is horrible Im just trying to learn by doing myself but I can’t figure out what the problem is. Please help.
Can you adjust your idle via the idle adjustment screw on the throttle body to compensate for the low idle?? If you did what rpm is your idle and how low will it drop before you stall??
I tried adjusting the idle screw when the idle got super low. I’d guess maybe 300-500 rpms. It prevented it from stalling. But once I get to my destination and turn the car off and the engine cools down, a couple hours after that I’ll go for a drive and the idle is now obnoxiously to high. So high to the point where if I just put in drive and not touch the gas pedal i could reach 15mph on a flat road. Before touching the idle screw my rpms would be normal around 800 to 1,000 rpms I’d say. Then once I drive for about 30 miles or so and come to a stop that’s when my rpms drop to about 300 to 500 rpms
Let me know what you find. I am having a similar issue. Mine will stall sometimes after cruising 45 mph+ for an extended period of time. I can't find a vacuum leak and my gas mileage not so great for a 22RE. I've just been too lazy to go dig around more.
How do you know your TPS is fine? How’d you check it? Did you calibrate it? Also, did you check if your injectors are all spraying? I’ve had the same issue two years ago, but I want to know what you’ve done to check the TPS and how you checked it.
When you say stall, do you mean it starts lagging or bogging out while cruising? Also, laziness causes problems. Lol. Get your ass up and research bro!
