Husky Posted July 4, 2015 Share Posted July 4, 2015 Hi all, I have a 1999 OBW 5MT with ~175k on it, and I've noticed that it's running a little rough. It's definitely not too bad, and is quite livable, but I'm wondering if there might some cheap fix. The issues I've noticed, and I'm not sure they're even related, are that the idle is a bit rough when the engine's warm, and that the entire car jerks a bit if I come off the throttle too quickly. It also usually takes more cranking than I think a healthy car should to start. I'm pretty sure the issue isn't electrical, as I recently changed the spark plugs with ones recommended by my mechanic (I believe they were NGK irridiums.) I also changed the plug wires when I did this, as one had a torn boot. The battery is healthy as well, as tested with a multimeter. Anyone have any thoughts on this? I would think maybe to start by trying to clean the idle air control valve? Thanks Quote Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted July 4, 2015 Share Posted July 4, 2015 (edited) no oil on the plug wire boots? was the timing belt system serviced at about 105K miles? One thing that kinda fits the symptoms would be a bad Engine temp Sensor keeping the car 'choked'. Some data from the ECU might help confirm that. There may also be an ohmmeter check in the FSM for that sensor - others may know what to look for.
