Andy FitzGibbon Posted February 24, 2013 Share Posted February 24, 2013 Because I have been too busy to do it myself, I just had a bunch of work done on my '96 2.2 (5 speed) OBW: Timing belt and associated parts (seals, water pump, thermostat, ect.) New front 02 sensor New knock sensor New plugs and wires New PCV valve Before the work, the CEL was on and the computer had PO420 (catalyst) and PO325 (knock sensor) codes. Once the two sensors were replaced, the CEL turned itself off after the usual number of starts. But, ever since the work, the car has had a surging idle. It will almost die, then rev up to 1k RPM, then almost die again- in about 1 second cycles. Any ideas? Maybe MAF or IAC? Other than the wonky idle, it runs and drives just fine and gets the usual fuel mileage (about 26 with oversize snow tires). Thanks, Andy Link to comment Share on other sites More sharing options...
Fairtax4me Posted February 24, 2013 Share Posted February 24, 2013 Checked all the vacuum hoses and intake tubing for proper connection? If that all checks out you might try spraying some throttle body cleaner through the Idle control valve in case it is sticking. Link to comment Share on other sites More sharing options...
