:doh: so hang on, you've taken one of the leads off? and now running it with all of them minus that one you've taken off? Yes, that will run like a bag of crap. Your only using half your engine...

Hey lufcp,

Do you mean taking the spark plugs off and then trying to start the engine without them being connected?

if so then yes like adam has said the car would run like a bag of bolts because your only using 3/4 of your engine

how long has it been since you serviced the car?

Clean the throttle body using carb cleaner

hi bredsticz,yeah ive cleaned the throttle body,still same prob,although car is faster now,how can i test the coils and ht leads,thanks

I think you can use a multimeter to test the HT leads by doing a continuity test (ohms reading) to check if there is any resistance in the lead as the there shouldn't be, just remove the HT leads completely and connect the multimeter to both ends if the reading comes up 0 the lead is fine.

I don't know about the coils though, i think this info will help though =]
