as above, had my amp bracket powdercoated with other parts & refitted it, cars running but since engine rebulild/powdercoating it judders badly on low revs when driveing it??????

wierd as it ran sweet b4 & only gave it a freshed up & put it back in & now it doin this????????

so just a thought???

ive changed tps as thought it was that but still doin it.

cheers

 

Which other bits have you powdercoated?? could be an earth somewhere else, ie the inlet manifold if thats been done.

 

nah inlet was painted, car runs fine but if i try drive it at low revs it judders like a bitch most of the time.
u can put ur foot down & it will clear but is really annoying the shit out me.

other parts were just engine bed, tanks strut brace etc... nothing that will cause a problem.

justnot sure if amp is mounted on plate just to mount it to innerwing or it has to be earthed?

but i would have tought it wouldnt run atall if this was the case

 

Sounds TPS related to me. You have another tread open with TPS fault. Are you sure you have the correct TPS fitted to the car, as the PF01 and PF09 read the opposite way to eachother. Mine had this issue when I bought the car, it had the wrong TPS fitted. The Ecu will think its on WOT at idle and overfuel, possibly causing your High CO% at idle. Mine drove ok at mid to 3/4 throttle as both TPS's will read similar at this point.

 

pretty sure it needs eathed,on the amp i think you can see the metal terminal where one of the screws would earth it from,
think plate it screws to it would earth to inner wing,
did you put paste stuff between amp and plate?think it stops amp overheating,

didnt put anymore stuff on back on amp as there was still plenty on it.

maybe worth nicking my mates amp/bracket off his & trying it on mine just to eliminate it.

 

yer it was a 2wd tps pf01 as brought it from a breaker


think ill try mates ignition amp then run it to a local rolling road centre & get it set up as have brought a msd chip for it aswell so get it all done/fitted at same time

 

you could make a wire up and earth it to battery to check
