RobertISaar Posted May 31, 2013 Report Share Posted May 31, 2013 scan data. otherwise, you could either tap on it while the engine is running to see if it causes the engine to react, or unplug it and see if the engine runs better that way.

J.r. Patton Posted May 31, 2013 Author Report Share Posted May 31, 2013 I know if you unplug it the idle jumps to about 3k. Its just a little sluggish on acceleration. no check engine light is on either. Quote Link to comment Share on other sites More sharing options...
