Engine Performance problem
1999 Porsche Boxster 6 cyl Two Wheel Drive 78,000 miles
after taking off tb for cleaning including idle air control valve, and putting back together, the car will start but idles really bad and when I give it gas it backfires and won't idle above 1000 rpm. I also have a cel after installing k& n air filter. Took out maf sensor and cleaned several times, put original filer back in, erased codes (1123/1125/1128/1130), but it keeps coming back. Any way to check these 2 sensors with multi-meter?
