Hi guys,
Not quite sure what the problem is....but since last Thursday after Larry manually turned down the boost for my turbo (by adjusting the wastegate), the check engine light signal comes on after long drives (~30-40 mintues). And when this happens, my idle fluctuates back and forth, and the whole car seems to be "choking," or rather hesitant. However, after I reset my ecu (pull out the 7.5 from the fuse box), the engine light goes away, and the car goes back to normal.
I suspect that it might be something wrong with my 02 sensor....but not quite positive. Larry replaced an aftermarket 02 sensor when I first got my turbo months ago....Not sure if it is just defective or burned.....what might be the problem? Thanks.
JACK
