Focus Help

I purchased a 2001 Focus, Vin P , SOHC---5 speed manual shift---4 months ago had new timing belt -and everything with it replaced , including a new camshaft sensor-- Just last week 2 new problems have showed up ---I do have a code scanner--it shows me NO codes, #1problem a bog or stumbling when i try to accelerate with a heavy foot---on my scanner it shows the timing retarding during the stumbling--i dont believe this is normal? My friends tell me that the TPSensor is the problem? #2problem--my speedometer has began acting like a tachometer??? as im driving it would go up to 60mph--and then go back down to normal?? Just this morning--when the engine started started--the speedometer reved up like a tach---to 60mph-- then went back down to Omph?? I hope some one here could help me--Are these 2 issues related to each other? I never lost my desire to wrench on cars&harleys--But computers and sensors--are a little ahead of me now. Thanks for listenin--Ray

The speedo isssue might be the velocity sensor, but if it is intermittent, a wiring problem seems likely.

Two issues could be related. Speedo problems could cause your car to think it hit the governor, causing an intentional temporary timing retard.

I hope you find an answer to this problem as mine is doing something similar. The speedometer wobbles occasionally. I read somewhere that it could be a grounding issue. Maybe try cleaning your ground wires, idk.
