Rough Idle

[Trevor loves holden.]

IAC for rough idle, flat spot can be spark or fuel, TPS might be the first thing to change or test if you have a multimeter, it should clime steadily to 5v full throttle if it jumps up then down its stuffed. If you can pull up the fault codes..

I was getting rough idle symptoms a few months before my alternator died. Could be worth checking too

Would you believe, it was the coils?

I swapped the coil pack from my VX to the VY and it is running perfectly again

Thanks everyone for your help. Yous are champs
