2002 Buick Rendezvous CXL will idle very high & idle too low & stall when going slow or stopping.Replaced IAC valve. Service engine soon light not on, but service vehicle soon light always comes on.


Check for applicable trouble codes. Some of the national brand auto stores will check codes for free.

You may need to clean the throttle body and clean those small passages. With a high idle block off mouth of throttle body, should have a big effect on the idle? There are several issues that could cause idle to act up. Vacuum leak--maf and or map sensor. Don't replace anything unless testing points you in that direction.

Can position sensor, maybe, or it might be called a pick-up coil. This sensor is needed along with crank position sensor for computer to determine spark timing.
When you get it started, and if you still have the up and down idle, check for an intake manifold leak.

STALLS WHEN STARTED UNLESS I PRESS GAS


the iac code has nothing to do with the maf . the maf is your mass air flow sensor and it is in the air tube going to the throttle body. the iac is your idle air control valve that is in the throttle body next to the throttle position sensor

Check engine lights on 99 ford ranger ODB codes 3- need solutions before in shop takes me to the bank help #1- P1506 #2- P1131 #3- P0171 I already know what they mean, got them written down. Need...


DTC P1506 is set when the PCM detects the engine idle speed is greater than the desired rpm. This is most commonly caused by a dirty or bad IAC valve. Cleaning the throttle body will, most likely, cure this problem.

p1131 means that the bank #1 O2 sensor, the bank closest to the firewall, cylinders 1-3 is showing a lean mixture. Could be a vacuum leak, a misfire on that bank, an exaust leak upstream of the O2 sensor, fuel control or injector problem on that bank, a faulty O2 sensor, faulty PCM, faulty wiring in the engine control wiring harness.

P0171
In the vast majority of cases, simply cleaning the MAF sensor does the trick. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling also Inspect all vacuum and PCV hoses, replace if necessaryCheck for a dirty fuel filter and proper fuel pressure

Idled high, replace IAC and PCV, now idles low and stalls


On modern day cars the parts that get fitted need to be adapted to the ECM using a decent diagnostic machine. I bet that this was not done and the car is now suffering as a result.
Something to try is resetting the ECU, simply disconnect battery for 10 minutes, reconnect, then start car from cold *without touching gas pedal* and leave idling until the rad fan comes on (this resets all the base idle settings) then take it for a drive - hopefully will solve the problem

1990 Buick Century 3.3L Check Engine Light comes on, stalls.


Need to check for fault codes. Possibly a faulty sensor causing the fuel system to run rich or lean.
