Ok. Got Temp rego, and got insurance with Shannons.
Took the car down to workshop on Sat morning... same thing, car heats up to normal operating temp, and starts running like shit, and the lights come on.
Was driving on "a" hwy, so i could open her up a bit, so just get driving it, doing laps of the hwy. Some times the power delivery got kinda jerky, like it would rev to 5K, then like drop back, then kick on again. But after some more driving, started to become smooth again. Turned car off/on, and the lights went off. So now i'm thinking, it just need a "real" drive, not something just around the block.
Bring car back into workshop, plug in scan tool. ECU has logged 'Code 21' - some sort of ignition problem. So it's most likely the coil packs? - Got the scan tool to clear the codes, and the car was fine. Even though it's running fine, should i still change the coil packs?
anyways, so yeah. Code 21, i'm guessing that's the same prob you've got there Ryan.
