R34 Hesitation & Cut Out On Start Up

[so_tred]

I posted a topic a few weeks ago about this problem but didn't get anywhere so I'm here again with some updates.

The problem is that my car developed a hesitation while cruising. No engine lights came on the first few times however after a while the SLIP light would come on & stay on (TCS turned off). Lately at times the engine light will also come on with the SLIP light.

Took it to a workshop who ran the ecu error codes and came up with the code for the AFM so I bought a brand new generic one and still have the same problem.

It's slowly getting worse & worse with it having a extremely tough idle on start up this morning then cutting out completely.

Ideas?

Sounds a bit like the coipacks.

When they start letting go, it brings on the TCS and SLIP light, sometimes the ENGINE light as well. And loss of power and hesitation.

I would be thinking coil packs as well but it has Splitfires. They were put in about 50-60,000kms ago but I'd expect them to still be good??

Engine light + SLIP is typically caused by busted coil packs. Next time they light up have a look at the ECU fault codes - the paperclip method is easy to follow. If you get 21 (ignition signal) it's 99% certain it's the coil packs. 50-60k they should still be good but you never know.

I've had a look at the codes and I'm getting 11 which is the AFM - have tried a brand new AFM and that hasn't fixed it so the ECU is no help in this situation..

Maybe it's as simple as a bad connection on the AFM plug. Or a faulty bit of wiring somewhere.

Some contact cleaner (or even WD40 works) sprayed inside both sides of the connection should make sure it's getting a nice clean electrical connection.

Good luck
