just put a c20xe dispac engine in a corsa b, its been fine for the first 10-15 miles, then on a trip out today it started loosing power and bogging down, pulled over, and it ticks over fine, rev it up and it misses and pops abit, but..... if you turn the car off and re start it you can drive fine for 30 seconds and it does it again, or.... if you thrash it it wont do it at all, its just under normal driving?
ok been out in the car today and its fine for the first 2-3 miles then when upto temperature it does it again, revs between 1-2k and has no power and slowely dies under acceleration, turn the car off and on and its fine for the first 30seconds.
