Re: engine check light Just to update, my EGR is sticking intermittently on warmup, so I have a little rough running for a few seconds. I'll take it off and run some good cleaner through it with a nice rough steel pipe cleaner. After that I shouldn't have any work left on the truck - apart...

Re: Details The truck hasn't been running right for a while. Started with a surging idle when the engine was warming up. The idle would jump 200 - 800 rpm - not all the time, but occasionally. Engine started running rough on warmup. I could hold the rpm at 3000 and watch the engine drop on...

problem solved Throttle position sensor:50cal:

I have a 94 4Runner with the 3.0L. On warmup the engine surges at idle and if I rev up to 3000rpm it drops 800rpm and runs rough. Looking at the Haynes manual for checking the air valve it says when the engine is cold the rpm should drop when the idle adjustment screw is turned closed. If...

PCV fixed the problem

mechanically everything works. My light doesn't come on when the window goes down. The light does go on when the tail gate is opened. So where is the switch that triggers the 'backdoor' light when the window goes down? I see the switch that is triggered by the lock, and I'm assuming the...

(not a chance the oil companies will) If you don't mind paying around $5/gal then the refinieries (not the producing oil companies) would be glad to produce as close to 0 sulfur gas as they possibly can. The fact is for oil to go to the refineries from the oil companies the sulfur content of...

still error code 25 Well now the check engine light is intermittent and so is my idling. When the truck idles it oscillates to lower and lower rpm until the engine quits. I'm replacing the pcv valve... maybe that will fix the idling problem. One interesting note is the exhaust has a really...

Anybody know exactly where the switch is that triggers the 'Backdoor' indicator light? 'Backdoor' light comes on when window is full up and goes off when I toggle the rocker switch to bring the window down and right back up. The indicator light does not come on anymore when the window goes...

I got the engine check light. When I check the code I get // ///// (error code 25). The O2 sensor has less than 10k miles on it, the ECM works fine. I have had a problem with the engine acting like it is missing, but that has cleared up on its own, now I get the engine check light. The...

I checked out the ignition system - ok. Turns out I needed a new fuel filter. The truck still has a slight hesitation when I maintain a level of rpm cruising around town, after the engine has reached operating temp.

I am having a problem with my 3.0L V6 (I have a 5 spd trans). When the engine is cold it stutters and hesitates. It also acts like it's running on 3 cyl. before full power returns when I step on the gas. The problem is more noticeable when I am in high gear or 4wd. When the engine warms up...
