Seemed To Fix One Problem.. Need Help Eliminating The Last One.

[willzgtst]

ok, so i have fixed the issue of the car stumbling and stalling after 20 minutes by adjusting the TPS, and replugging it in firmly has seemed to vanish the problem. Now i have some other retarded problem.

when im driving, it doesent cut out its more when u plant the foot down and gear change i cop a power cut every now and then.

is this the AFM being a Cvnt ? or is this spark plug related ?

its not anywhere near as bad as it used to be, i would love to be able to Eliminate the problem

btw its an auto.

Plugs, coil packs.. How much boost?

[willzgtst]

boost is nun spec. ( stock ) LOL

plugs are ok and coil pack is fine.

i got it booked in next week for a diag, and then a service also. so if i dont figure it out by then

ill have another look at the coil packs for any wear. but other than that i could probably say my AFM is a non nissan and its buggered...

thanks defari.

oh, xD Same thing happen to my car. I changed the coilpacks and it is all fixed. The coilpacks must have cracks that allows some of the sparks leaked out. Correct me if I'm wrong but it is one of these:

Spark plugs

Spark plugs leads

Coilpacks.

Do you have a blow off valve ?

I blocked mine off which removed this problem, but along with that I also cleaned my coilpacks and siliconed them up.

Regapped plugs.

Open the AFM and check out the solder joints, if they're dry, then re-solder them.

If it occurs in gear change (meaning no load) wouldn't this remove the chance of it being a coilpack issue ?

Cooler piping, vac leaks etc.
