Yesterday Penelope developed a rough idle while waiting at a light. Ran OK any other rpm or speed traveled. Happened several times then the dreaded "engine icon light" went on.
Headed to the dealer this a.m. Dealer tech put the diagnostic tester on it and found all four cylinders in the right bank had misfires. Cylinders number 1, 2, and 4 (forward to back) had misfires in the hundreds, while 3 had over 3400 misfires.
He thought the emission sensor was gone....again. Had it replaced about six months ago. Was about to replace the sensor when he noticed, on then opposite end of the sensor cable, the four pin connector end to the wiring harness was badly corroded. Actually looks like moisture has been building up over a long period of time, blocking out some signals sent to the emission sensor.
The tech replaced the corroded pins, sealed the back side of the pins, and taped over the connector to the wiring harness. Retested and all was normal after the sensor warmed up. Warranty item #8 complete.
Anyone else encounter a problem like this??
