It could be either a vacuum or a fuel problem. Sounds like you have the ignition covered. If the engine light is on have Autozone check it for codes they do this for free. No codes I'd check fuel pressure if it's low you've got a bad pump or faulty regulator.

I went to go get my car inspected and it wouldn't pass because of a code P0106. I want to explain how my car is acting when started especially when its cold out. The colder it is the worse it starts.


I'd be more inclined to the cold start side of things. Relay, cold start sensor. Water Temp sensor not activating the cold start setting.

The lights going dim could be something else completely

Stalls after start up, Stalls when braking, then runs fine after a few minutes


Check the ECU engine temperature sensor. If it thinks the engine is hot, it will struggle to run when cold.

Check the idle fuel pressure. Load the electrical with headlights and heater defrost etc and see if problem gets worse. Attempt again with all accessories off. Could be fuel pump is getting low voltage at idle or fuel pump is failing. Bad fuel pump would definitely be a problem high fuel demand. Check vacuum line between pressure regulator to intake manifold.

Check for a air leak in the intake manifold. Gasket/hose etc. The P0171/P0174 is an indication that not enough fuel or tow much air. You can sometimes hear the air leak during idle.


Best solution is to use a graphic capable scan tool and watch the fueling trim/idle.

1997 3.4l 4runner misses at idle when first start


The coil packs on these engines will show signs of Arc tracing. Its a white shadow or line that runs along the rubber boot. if you see this. Suspect that coil of grounding and causing a misfire. Misfires usually occur after an electrical part is hot, the rough idle for the first 30 seconds sounds like another issue altogether, especially if it goes away after 30 seconds. Misfires from coils dont usually go away,,,,, they just get worse. Good luck .

Runs like ****


you dont need to ground your ht lead, infact that could damage your ignition system, if in fact removing it from the plug does make it worse you then know that this cyl was firing and that ignition on this particular cyl is not your problem.
