Question about 1998 Volkswagen Jetta
T have a golf 2000 2.0 aut. the problem is on a cold start it grab the choke.(does not rev high). IT REVS AT 500 RPM. after a while after holding the pedal down, until engine warms up it rev's normal 950 rpm.there is no check eng lght on. dis a scan test found nothing. changed the coolant sensor, same thing. im thinking of cleaning the throttle valve whats your opinion on this
Here is the most common cause of surges and stalls and low idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake
