Title: Another fault... misfire and strange throttle behavior
Post by: octanejunkie on 09 August 2014, 15:17:17

Right, another fault has reared its head this afternoon..
Since rectifying the cam sensor fault, i've been running about in the car happily all day with no issues. However, this afternoon i go to start it, and when it fires up it is lumpy. If you put your foot down, it just bogs down and stutters around 2800-3000 rpm. Lift your foot to around quarter throttle and she'll rev ok. Try to coast on a light throttle and it stutters and misfires too. At idle it is threatening to stall, and hunting badly.
There is no eml showing.
This car is doing my head in now!!!  :(

(assuming it was a genuine sensor), misfires with no codes on these are normally HT related, so that's first port of call.

If a visual inspection of plugs, leads or CP doesn't reveal anything, just try it with the MAF unplugged
