Hey all,

Atm it is averaging 40 degrees everyday for the last 2 weeks. Ever since the heat kicked in, my car has been playing up.

When I reach about 2600rpm, the car will start to jump, like roo hopping, until i change up a gear. It will do this through every gear.

It has only started doing it the last 2 weeks, and I have owned it for 3 years and never had this problem.

Then today, crossing in intersection, the car just died. So started it up, and on the 3rd try it worked and I drove off.

I am restriciting driving it only to work and back.

What could it be?

It is an R32 GTS, 5 speed.

could be a few things. could be the coils, could be the ignitor. they both suffer greatly from heat issues when they are on their last legs.

is the problem like it is dropping a cylinder or 2? if so then i would be looking at the above suggestions. if it is a dead cutout of power then it could still be one of the above issues, but it could also be a coolant temp sensor issue, or an actual engine temp issue.

I did have this problem once before when I first go the car. Was not always happening in hear though. Had to get a new one.

Maybe I'll try cleaning it and spraying some contact cleaner on the wires to see if that helps.

sounds like an AFM problem to me.

I agree, my afm shit itself a month or so ago and it was giving me the exact same symptoms.

I gave it a clean it it made no improvement, so i re-soldered where the plug joins to the board and all my problems were solved

    • Yeah I also looked at Plazmaman, but, it ended up alot  cheaper getting black ones through EFI when you also added in the delivery cost
    • Nice shot! They look super clean. The roof rack delete on the black one is interesting. Would like to see more pictures from different angles. It's subtle but could make quite a difference to how the car looks in profile.
