hello!


just had a piper cam fitted and run in - the revs every so often drop down very low and 2 stalled the car

the car hasnt been driven apart from taking to the garage before fitting and it was fine then.


is this normal and do i need to adjust something?

 

i would check all the boost hoses and breather pipes etc are all on ok, somethin like that can stop it from idling

 

it doesnt do it all the time - just every now and again


most of the time its fine


will check these 2moro thanks

 

everything seems to be fine - it seems to be related to having the piper cam fitted

it also does it if i come to a stop without the brake



but not all the time

 

Unplug the ecu for a minimum of 20 mins to reset its KAM settings, then drive around for 10 (ish) miles under a variety of conditions to let the ecu learn about the new cam. If this doesn't work it could be your VSS has failed (or did they disturb it when they fitted the cam?).

 

sorry mate - not up to date with engine talk!

whats VSS? will try the ecu when i get back from this private job in 30 mins then

 

KAM = the ecu's 'Keep Alive Memory' for storing error codes and adapative learning information.
VSS = vehicle speed sensor

 

thanks - i have the battery disconnected at the moment so will reconnect in about 1 hour

 

disconnecting the battery for a few hours didnt make any difference

and it seems to be idling even worse now


does it just need the fueling/emmisions set up after the cam fitting?

 

try disconnecting the idle speed control valve ( with the engine running ) then reconnect and let the engine idle for ten minutes, the revs may be a little up or down during this time.

 

ok will do..... you dont think its anything to do with the cam then?

 

Check your MAP sensor is plugged in properly, its at the back mounted near the bulkhead.

What cam was in the engine and what one has gone in? Also did it have new followers ?

 

standard ford cam

replaced with piper fast road cam - it was a kit so yes it did

 

mine actually had this problem, doesnt do it anymore like, all i done was check all my hoses and choped one of them a little bit as it was a bit to long, one of the bolts holding my turbo in was a tad loose so tightend that up, i think im loosing air somewhere but unsure where, i turned up my rev's with the little screw in the arm that your accelerator goes to, ive added a pic to show you what i mean lol, i just turned mine up slightly.



on the picture where ive circled there a little crew under the bracket, you can make your rev's go up by turnin it but dont put them up to much

 

been to power engineering today to have the engine all setup and tested etc etc

he was playing about with what you circled so i think you were right



20% leakage in cylinder number 4 and a slight drop in compression

he also thinks i have a slight knock

so now i will be buying all the stuff for the zetec bottom end conversion

 

bad news but at least you can get a zetec lump in cheap enough nowadays
