  1. Cleaning the IACV and the MAF fixed the trouble for about 2 days, then the car returned to "normal": losing power on acceleration at about 2500 rpm, wandering idle from 750 - 2000 rpm. The CEL is came on though, and the codes are P1100, P1507, and P0443. I went through some of the service records from the previous owner, and it looks like something was done regarding the MAF and a recall; the service sheet is pretty faded but it mentions the MAF and a recommended defect service. Thanks, John
  2. Thanks for the ideas! Forgot to mention, there has been no engine code so far. Plugs and wires are less than 1 year old. I'm sure the O2 sensor has never been replaced. I'll start with the IACV and see if a good clean out sorts it out. Thanks for the ideas.
  3. Hey guys, I've got a 1999 Legacy wagon 2.2L that loses power during acceleration. The RPM's fall for about 5 seconds, then the engine suddenly accelerates hard (if you keep the gas pedal depressed). This happens at about 2,500 rpm pretty consistently. The problem seems to go away after the car warms up for about 20 minutes of driving. A second (potentially related) problem is a wandering idle. The car idles at 750 sometimes, but wanders up to 1500 or even 2000. I'd appreciate any thoughts! Thanks, John
