*Scotty, thanks for your kind attention.
I hope you and family are well and happy.
About 20,000 miles, the mechanic replaced the module satisfying the OBDII po121. However, after a few miles, the feeling of bad fuel or bad pump action. The mechanic doesn't want to hear from me. Just hate the "ignore" attitude of supposed professionals.
Please advise.
Thanks again!
Steve
PS, Grew up in Boise Idaho in the old Northend during the 50s and 60s. Every neighborhood teen boy and college man seemed to be busy working their own car/rod/dune buggy/hunter's rig - hogs and boats. Mechanics really looked the part. (One neighbor recovered Model As and Ts - he and son built a 1x1 seat roadster for travel through Europe and Russia - during the middle 60s). Wanna change this weird American society? I think we should make it legal, tax free to build and sell vehicles at the local level.
Where those codes odds are you have two separate problems, one the sending unit and the gas tank is breaking down. The other would be that either your throttle position sensor has gone bad or the wiring to it has gone bad or the throttle motor has gone bad. That last one you'd have to test to see which one it was
Thanks so much.
Handshake bud!
