    02 chevy s10 4.3 vortec wont idle barely starts

    Be sure to check the Idle Air Control Valve...can be just dirty, or may need replaced...also thoroughly clean out the throttle body, spray and wipe clean...also clean the Mass Air Flow sensor, it requires a specific spray that does not erode the unit...hope this helps.

    It starts but as soon as it's put into gear acts like it wants to go but quits.

    Could be a few things. But here are the obvious. Check for a vacuum leak around the intake. When you put the car into drive it starts putting strain on the engine, a vacuum leak will give it too much oxygen and cause a fuel mixture issue / reading.
    If nothing wrong there, you may have a bad throttle position sensor. When you put the car into drive and it starts putting strain on the engine it will pull the idle down then the sensor will adjust it automatically. Hope this helps.

    2.2 litre 1995 gmc sonoma idles rough no trouble code. found hole i brake booster vaccum line fixed that. replaced and changed fuel filter, idle air control valve, got spark at coil packs, put new spark...

    Three things you should check using a good code checker which can read sensor outputs - the throttle position sensor (TPS), the mass air flow sensor (MAF) and the EGR valve. While you are at it, replace the PCV valve.

    My 98 taurus has this codes what do i need to fix? p1518.p0174.p0

    p0171 and p0174 are o2 sensors, There are 4 o2 sensors on a Taurus. 1 on each exhaust manifold, and 1 after each catalytic converter.
    p1518 is vehicle speed, idle speed control----this means the idle air control needs fixed. you can take it off and clean carbon from it. do not push on end of air valve it will loose its adjustment. do not put in any liquid to clean, the best way is to clean end of valve with an old toothbrush or similar. also clean carbon from engine side where iac mounts. when clean put back on. you can use carb cleaner for end of valve, as for the 02 sensors, you have to find out which ones are bad first. or replace all thats up[ to you. you have to get a 02 sensor socket for 3/8 drive. then they just turn out. the best way to get them out is have the car warm.

    99 volkswagen beetle 2.0 engine problem

    Cat is usually damaged from vehicle misfiring, Those codes you posted are a MAF, idle control, and 02 sensor codes. The MAF sensor could be reading incorectly causing the car to run rich or lean, and giving the 02 sensors bad readings, i would deffinetly look into the MASS Air Flow sensor, which is located on the intake tuping near the airbox

    You can also try cleaning it with MAF sensor cleaner

    I had the same problem. I changed out the idle air control valve and that solved the problem. Somehow the electrical connector fried out some of the pins.
