Car Jumping In Hot Weather

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

      Rb26/30 build

      By lilley's gtr · Posted

      I've been building a 26/30 for a few years now. I've had the head built with all the good stuff. I had a 32 gtr but blew it up and yes its all going into a vl but im looking for some advice from some RB nuts on pros and cons on putting a 26 head on a 30 bottom end is it worth it Works are as follows Head -Extensive porting 1mm oversized supertech valves Supertech double springs Supertech valve guides Supertech titanium retainers Tomei solid lifters Tomei 270 x 10.25 cams Head drain Bottom end series 2 rb30 block Cp ceramic coated pistons Eagle rods Romac balancer Oil restrictions  O ringed blah blah spent a fortune And will get a girdle because the 30s arent used to handling that much rpm Nitto billet oil pump Hypertune plenum 6boost mani Refurbed astra pump thats the cover for it in the boot I did have a precision 6262 but sold it because drag car life. Currently building the ass end full 4 link floater rear end with a 2 speed  But the dilemma i have is my mate rekens I should just stick with the 30 head for reliability. Has any one had any issues with mounting the 26 head ie compression blowing gaskets etc. Just looking for some advice from people who have gone down this route. Here's some photos. Blew the oil pump in the gtr and decided to rip the motor out at the time and do a full build only to find it had been a repairable write off so went down this path.

      Nismo rear spats

      lol no cats running str pipes … might put the high flow back on but I suspect it might effect my ignition timing a bit.

      That looks a bit like yellowing to me. If the rear bar was looking like that from rich idle, I'd ask the question, do you have a catalytic converter fitted, and fully working?

      Oh yeah gets really bad down here. I’ll have to upgrade the heater and wind screen wipers as well for optimal performance.
