north scotland help
Im up in Thurso and having probs with my sub, anyone up here or at least inverness or above good at checking sub engines?
Main prob is when engine is cold (ie. first thing in morning) it hesitates now and again when driving, also when left idling at cold the revs are very irratic and looks to be dropping too low and almost stalling engine (this must be whats causing it to hesitate when driving). Car runs fine once hot.
Last night appeared to get a flat spot at medium/high revs in 5th, then came back to life but Check Engine light came on until i dropped my speed back down.
Went up to speed again and it was ok.
Have serviced the car since prob with hesitating started but this made no difference.
Its a 93 import WRX.
Any help much appreciated.
Cheers

not great with tools really, me and a mate changed the spark plugs ourselves,the coil packs are on top of the plugs aren't they?
How do you check the coil packs are faulty?

Ok, if you remove the coil packs from the spark plugs, take the rubber boot off the top of them and have a good long hard look around the top of the pack. You should be able to see the join where the 2 halfs of the pack is sealed and NO other cracks. It's usually hair-line cracks if anything. I've seen them completely break up-worst case scenario.
The ICV is on the right of the throttle body, attached to the inlet manifold. Remove the 10mm bolts and give it a good clean with brake cleaner into it. Hopefully should do the trick.
