Rough Idle
Hey Guys, I'm having trouble with the missus's VL. Over the last couple of days the idle has gone rough as. It's an RB30, auto that's stock bar a set of pacemakers and the 'zorst.
I've checked all the ignition leads and they're all fine so far as I can tell. Anyone got any ideas? |

Misses and idles really low? occasionally stalls ? Drives ok ???? sorta but sucks more fuel than a worked v8? I had one like this! o2 sensor turned into a lead pencil. replaced the sensor, did buggar all. changed the computer. Ran sweet. |

Computer replacement was $20 and is behind the kick panel of the passenger seat. 10 minute job.
If it is the computer ? you can replace the sensor straight away or go for an hour steady cruise somewhere to burn the carbon of it. after about 20 mins it will be ok. The Motherboards in the computers are susceptible to corrosion.. its not uncommon. |
