Car Hesitating, Coil Packs, Afm? Got Me Stumped

[R34gymjunkie]

Done a bit of research but want to know ur thoughts, since getting my 3" turbo back my car has been hesitating when on boost and only sometimes, only happens when the car is warm or on a warm days, plugs replaced and gapped at .8 (bkr7es), stock intercooler, running 12psi (r34gtt), once the car hits 5500 it picks up goes great, and if I feed the accelerator on slowly it doesn't hesitate, I was thinkin coils or afm?

Sounds like your on the right track there.

Guess who has a full set of low KM Genuine Nissan R34 GT-T coil packs.

PM me if you need them.

12psi on a stock ECU will hit R&R (rich and retard), probably hitting the limit of the factory sidemount also.

^^ we he said

Where can I find some info on this rich and retard? Not familiar with it? Did do a search, might wind the boost down a bit and see how I go...

[KnightRiderR33]

coil packs i had the same problem with my 33 but then again i have a FMIC and 12psi sort of makes a sputter sound while climing the rev range aroun 4k -5500? if she hits rich and retart she normaly sounds like its droped a cylinder just pull over till the ecu fixes it self up

[R34gymjunkie]

Yeah that sound exactly like Wat mines doing, but not all the time, I can upgrade my intercooler next week or should I try coils first?

[R34gymjunkie]

Sorry read ur post wrong, its definetly rich n retard cos its fine past 5500, i am running the boost straight off the actuator(r32) might just buy a controller n wind it down

you can't wind DOWN below what the actuator is set to.

perhaps stick your stock actuator on and then use a controller to bring it up.

Or I could sell you an adjustable actuator I have

[R34gymjunkie]

Yeah I ment install a controller...

[R34gymjunkie]

Ok boost controller installed running 10psi problem was fixed but after giving it a bit the car starting idling high and now it's idling erratically from 1000 to 2000rpm...

[TTT]

That idle issue I've had before and it was because the solder in the afm had become brittle.

There are some DIY threads on here if you search for "AFM Solder".

Or it could just be that your afm plug has become brittle from removing it so man times.
