Author Topic: surges while driving 92SilverGT ¯ Member # 2729 posted                              i posted a reply about the "strange" idle ive been having. But ive also noticed that my car surges Hard when below about 2,000 rpm. ive tried raising my idle and it started doing it a little less but it still does it. im idling at like 850-900 rpm.

Also, remove the MAF sensor from the housing and inspect it, check for dirt and dust on the elements. If they are dirty CAREFULLY clean them off with the torn edge of a piece of paper. Otherwise you would need a high end scan tool like a Snap-on Scanner or a NGS to watch your TP, MAF, and DPFE voltage. Checking for continuous codes wouldnt hurt either, it might give you a place to start.
