hi noticed a slight blow in my exhaust manifold yesterday, went to drive the car it started fine as normal pulled off was ok for a second or two, then i had a big backfire and the car stalled tried starting again and it was idling very lumpy and kept cutting out, further inspection it had blown one of the intercooler pipes off aswell, so i re attatched that properly and it still ran the same if a bit worse, it could drive but would go 40mph max and wouldnt go above 1500rpm before it would just sort of misfire. engine and oil temps and oil pressure was normal and no engine warning lights apart from the abs one(as its removed). im no expert by all means so i thought id ask, only thing i could think of is that the hole in the manifold got blown bigger and there is no manifold pressure atall which is making it run like that as there is no other knocks or bangs and everything else seems fine. any ideas would be very much appreciated as i was out till quarter to 1 this morning waiting for a flatbed!!! and i miss it already haha!
