Took the S1 out yesterday and was fine, then when opening it up it hesitated or jolt then seem to hold back, I backed straight off but it happened again when I tried it again. The car has a fifth injector on it and it was towards top end boost. no smoke or anything came out the back and it runs fine.

Could it be the fifth injector not kicking in and starving it of fuel (I imagine this is not a good thing) and if it could be is there any way to test it.

Don't really want to try it again as I am scared of melting the motor or blowing it up.

Any help would be

Cheers

Matt

 

Could be plugs or leads breakin down

 

Andy, I just put new leads on it but neglected to drop new plugs in think I will get that done today.

Any other sugestions just in case

 

make sure you got them gapped right depends what sort of boost your running ? i was running 20psi on my old one and gapped the plugs to 25thou

 

i got this Mate, need to get it to someone ive tried alsorts!

 

Turned out to be plugs, new set dropped in sorted the problem, did it before but was more like car not pulling and was the clutch slipping so dropped and AP organic in, costly but worked.
