Stumped on bog-down source- Warning long post.... 700

I had a bog down on my '86 245 when I first got it last year...

it happened about 1 min. into driving after cold start...

that was the only time it was experienced... so my conditions aren't the same as yours, mine is not a turbo so that is different as well...

after about 6 months of troubleshooting I finally found that the O2 sensor had broken off in the exhaust stream and the sensor was failing to provide the computer adequate information....

there are several ways to check this but the easiest is to get an O2 sensor socket and remove the sensor... look at it to see if it is complete or somehow physically broken.

I replaced my sensor and the bog never came back...

this was after repairing vacuum leaks, cleaning flame trap and various clogged vacuum holes ... etc. - so it ran pretty good after that.

good luck,

jack
