ok, i thought this was a rev limiter thing but i've been told otherwise. I have an '86 n/a that doesn't want to run above around 3900 rpm when i'm in gear. If i'm sitting in neutral i can rev high as i want but not when i'm in a gear, going. I had a few people tell me that it sounds like my secondary injectors aren't kicking in but if that were the case wouldn't i not be able to reach higher rpm's in neutral aswell? Any ideas on the cause of this problem would be appreitated. thx -z00m

 

secondaries don't come on when revving in neutral, only under load. Check that and your aux ports

 

10-4 thx, hopefully i'll find an easy to fix issue.

 

Probably haven't been used in forever and are dirty and stuck closed/etc, that or it's a grounding issue with the ECU/dirty engine grounds.

 

ok, yeah after a bit of driving it (hasn't been driven in about 3 years) the secondary injectors kicked in and oh it was nice too >. They were just gunked up i suppose, so yeah thx for the help Sonic. -z00m

 

check the wiring too... the wires love to back out of the stock plugs.
