Hello
I have a 99 ws6 that is stock other than a lid and I installed a 3800 lockup stall converter 2 weeks ago and the car has been running fine till last week when I had my service engine light come on and the idle was going up and down so I checked the code and it is a p0102 so I cleared it and same thing happens then I find out from this website that there is a 20 amp sen. fuse which I replace and clear code again, drive for 10 minutes it happens all over so I cleaned air flow meter, not dirty at all, car just turned 20k miles on it this month and check all wiring going to all 4 o2 sensors and there is no breaks or rubbing anywhere so I borrow my friends air flow meter from his 01 camaro and reset the computer and replace fuse again and it happens again after 10 minutes I am so confused, I also checked all vaccum hoses, oil cap, dipstick and nothing is loose or broken, car ran fine for a week after converter install where do I go from here? Please any help? Thank you

Its not the convertor. I think you have the same problem it do right now. There is some spot in the wiring harness that is cut or rubbed thru and is grounding out and cauing the fuse to blow. problem is finding it. Could be anywhere in the harness but thats what it is.

I found the problem the next day, it was a pinched wire between the transmission and the floor board.
