i have an escort cosworth just been a pain in the ass from the word go but finely finished. The only problem is if i drive it hard through all the gears its fine ,but if i am at say 3000 rpm and in a high gear say 3rd 4th or 5th and go to pull it just coughs spullteres and u here turbo chatter DOES ANY BODY NO WHAT WOULD CAUSE THIS AS ITS DOIN MY HEAD IN AAARGH
ANY IDEAS PEOPLE THANKS

 

What plugs and gap m8 ?

 

MOTOR CRAFT .8 MM

 

071's ? What stage of tune is it m8 ?

 

Sounds like a TPS or map sensor problem to me

 

try a smaller gap - about 0.6mm will do

 

NOT SURE ABOUT WHAT PLUG NUMBERS BUT ITS T38 GREYS CAMS ETC AND HAS HAD ALL SENSORS AND SWITCHS CHANGED. APPART FROM TPS WHICH I HAVE AND IS READY TO GO ON SO IF IT IS TPS HAPPY DAYS.WHATS THE IDEAL PLUGS FOR THIS SPEC I WAS TOLD MOTORCRAFT ARE AS GOOD AS ANY

 

071's at 0.6 mm or denso's .

 

I hope you are not running this car without a TPS sensor fitted/connected.

You will melt it

 

.6MM IS THAT WHATS IDEAL AND WHATS THE HOLE NUMBER ON THE PLUGS CHEERS

 

finis code is 1120834 pal.

 

OBVIOUSLY NOT GOIN TO RUN HER WITHOUT TPS LOL

 

CHEERS

 

i found 2 sets of leads when clearing garage today fraser if you want to try them tomorrow

 

does a bigger gap give a smaller or bigger spark?? ive had my gaps at 0.88 and now 0.75 and still cant find the correct gap either as im having the same sort of problems when using boost.

 

Is your caps lock button broken too?

 

No lol

 

sorted the leads col cheers
