The wife has a 2001 GT SOHC stock engine.
This 80K car recently has began to stumble upon acceleration...and you can hear what sounds like a "mild" miss when idling. The only time this car seems to be doing it's job is at WOT.
- I've used throttle body cleaner on the TB
- Electrical cleaner on the MAF
- Cleaned/reoiled the K&N air filter
- Replaced plugs and plug cap wires
Several months back and for regular maintenance reasons only, I replaced the rear O2 sensors. I had intended on replacing the more important front sensors, but did not have the special socket to make that job easy.
In short, it seems the car is having issues when idling and/or under load. I would presume this is under Closed Loop operation. At WOT (Open Loop), I cannot discern any problems...she (the car) screams.
Would disconnecting the battery (ie. resetting the PCM) and reconnecting 30 minutes later provide any more valuable information to this forum ?
Any ideas or suggestions would be appreciated.
Thanks in advance.
