Question about 2000 Chevrolet Astro
Originally there was a code P0300. Also P1345 pending. I replaced a bad EGR gasket, cleaned some corrosion from EGR valve connector pins, and changed the spark plugs. Now I got a misfire code for #2 ... I'll check resistance on that wire tomorrow. The most noticeable problem is the surging at low rpms. It acts like the accelerator was being pedaled even when it's held still. Under load it works fine, although the surging is somewhat noticeable when cruising at highway speeds ... almost like driving into a gusty wind. I noticed the fuel trim numbers fluctuate a lot. Also the O2 sensor readings.
Disconnect your MAF sensor and take the Astro for a ride. If you notice an improvement; Try cleaning the MAF with CRC MAF sensor cleaner.
