i was driving around yesterday - when all of a sudden my engine reved up extreme - i shut down and pulled to the side of the road - i figured my throttle cable snapped or my return spring popped off.
so i looked under the hood and all looked ok and then i pulled up the carpet to see what was going on near my gas peddle but all looked ok. drove home about 5 miles after gettting a push to get started - different problem - al the way in 3rd gear, shutting engine down when i hit 60mph, made it thru several tricky intersections - finnaly stalled out two houses from mine because my neighbors where chatting in the street blocking my path home. two problems - the lever on my TB - several times - returned from full open to about 1/4 open - got stuck there? kink in throttle cable somewhere it think? cable are not twisted in center console. and it seems no matter what spring in put on my throttle body - it does not seem to pull it closed fully. can it be just gummed up?

I had a similar problem the throttle plate is not bushed and goes directly through the pot metal on the body. It gets warn and the plate starts t dig into the the bore which causes it to stick... I pulled mine apart and cleaned everything and and readjusted the plate stop. This is a temporary solution eventually I will need to install some brass guides. There was/is someone on the site that could do this but I do not remember his name. |
