when i bought my escort the ECU was nakered, car back fired when on over run when you dabbed the accelerator.

any how, its started to do it again

any one know where to get P8 re boarded as such?

 

P8's very rarely go wrong,how did you remedy the problem last time??

 

He bought another P8 off me

 

are you running normal coil ? or dizzyless?

 

Does the rev-counter jump about at the same time as the back-fire?

 

From what i've read on here, doesn't a rev counter playing silly buggers, and the car missing tend to point to the CPS?

 

That's what I was thinking...

 

THE RADMAN

im on coilpack

Mike Rainbird

i dont think so, will check again tonight and watch it, i am going to uplug the ISCV as its idling high too

Rolls

CPS is brand new,


also, on the SECS monitior, everything is fine


thank you fr the help so far

 

If it's idling too high, that indicates an air leak to me - check to make sure the FPR hose hasn't blown off (or any other hose). This can cause high idle and misfire (as the fuel pressure won't be rising with boost, so it will be running lean ).

 

are your ht leads well away from the map sensor? as this can pick up signals/interference from them

 

Mike Rainbird

thank you mike, but i pressuried the boost system and got no sign of an air leak except the slight hiss from amal valve

THE RADMAN

not really, im on coilpack, they run through inlet manifild, under top boost hose and next to header tank where the coilpack is, they always been there and this problem has only just started.

they are over 6 inch away id say

 

Thought you were rebuilding her???

Sounds strange?

 

inlet manifold may have a leak in it.

 

bigpower

that problem sorted now

dave cos4x4

tested it for pressure dave, no leak

 

i had a burnt out ecu bord in my one when i got it, sent it to Engine Advantages who had it tested and replaced the faulty parts.
( incedently i had a missfire / cutting out, that turned out to be a fault in the loom that burnt the bord out but the rev counter used to drop off at the same time. sorted the short and the ECU and has been fine...

give Paul a call @ EA 01376 502 522

 

DENNIS

thank you, will do some more tests hopefully and if cant find a problem anywhere else then i shall call him
