Car would start but would not idle, immediately shut off. Replaced throttle motor which kept car running but idling high 1250-1750 RPMs. Have not solved issue yet.
The engine on occasions will stop when approaching traffic light to stop and when slowing down to take a corner.. The engine seems to run OK but now and again appears to miss fire
My car will start but immediately shut off If I don't give it gas
The Idle Speed Control Motor Failed and damaged the ECU & the throttle chamber
Check engine light on and drivability issue. Hard to start, had to give gas and turn the key a the same time to start.t
Idles to high replaced idle control motor still doing the same plus it will die while driving
I bought this car with this problem thinking it would be an easy fix. I read up on the issues i was having " IDLE REALLY HIGH THEN REALLY LOW". I took the car to the shop code showed P5050? I tink. Showing IACV. I seen ALOT that of people with this problem cleaned there TB and never had the problem again. I cleaned my TB for 2 hours got it very clean. After replacing everything the car ran amazing like a brand new car for the rest of the day. Got out to drive it this morning and its doing the same thing all over again. Now after seeing that cleaning thet TB did infact do the job I am sure it is not the IACV nor the EGM. What did i do wrong? Did i miss something? Why did it run so good and then start messing up again? Please help.
Car would start but die immediately when not pressing the gas pedal. If you slightly press it will run just fine. I cleaned the mass air flow sensor . Then changed the IAC . I first removed and checked the ECU and didn't see any noticeable issues or dark spots. Put everything back together and still no idle. I was told it needed to be programmed or relearn. We tried repeatedly the manual process , crazy process , used a snap on analyzer and followed the prompts as well. Still no idle.
Replaced IACV, need to replace fried ECU now.
Replaced idle control but still will not idle
Gasket failed leaking coolant into IAC valve. Replaced IAC valve and gasket to repair.
The issued started when my car failed to turned over but immediately died one morning. It started on a third try and I drove to the store. When I put it into park however, the idle became erratic. On my way home, I noticed that occassionally the idle would jump up about 1000 rpms while driving. I smelled the burning and knew something was wrong. The check engine light came on and it was the idle air control (IAC). In addition, a chip in my ECM (ECU) had burned up. The chip was in 2 pieces when we took the ECM out and looked at it.
Have had to replace ECMotor and ECComputer
I don't know for sure what type of engine (DHOC or SOHC). I was driving in normal traffic, no "check engine" lights were on, and I smelt a burning smell. It went away in 2 mins or so...thought it was possibly the car I was following. 20 miles later, smelled it again. Car died less than 3 miles later and all the dash board lights came on...I waited 2 mins, then re-started but it died. Power steering was not working upon both stalls.
Car shut off while driving. Diagnosed bad gasket on iacv causing coolant to leak into intake, shorting out the iacv and the ecu.
The car starts fine idles o.k but when you drive after you get to about 1700 rpms the car gos into like a limp mode let it go back down under 1700 runs good .Have changed coil packs and the plugs showing code p1320.
My Nissan maxima front bumper is not good how much will it cost for me to buy and fix it right
IACV fails and shorts out ecu. I sent the ecu out for repair and replaced the iacv and the tps for good measure. Works well again.
