VR6 Running Issues :(

[Ratty 0]

hello, new to this forum seems like a nice helpful and friendly place. first post will be a tech one

just got a VR6 off me mate (vento) ne way it was a dissy car but he blew the motor, the new motor that he put in is a 2.8 (aaa) odb1 motor. however this was a coilpack motor and he made put a dissy on it. it ticks over but stutters a bit and the revs drop for a second, keeping constant throttle it stutters a bit too, and on full throttle it definately seems like its not performing proper.

so! what would be the best approch>? try converty motor back to coil pack and get a coilpack ECU?or try sort out the running issues? if so whats needed to get it back to coil pack?

(the motor hasnt got an airbox on it either)

Thanks Peoples

Do you mean your running without an airfilter????

I'd get the motor on vag com, see what error codes you get. If your running without a filter you might have sucked all sorts of crap up onto the MAF

no airfilter just a gauze over the pipe, im thinking it may well be the MAF. cars going in for vag co tommoro

right well after VAG check and fault clearing, the wierd misfire seems to have gone but still feels odd under throttle although this maybe down to engine mounts./

the faults where :

knock sensor (open circuit/short circuit to ground

sporadic

lambda probe no signal

sporadic

maximum speed exceeded

sporadic

these wouldnt have been cleared since the engine was changed, so i am now going to try get a vag com cable so i can see if they come back
