Checking and cleaning MAF sensors

Stored error codes take longer if you can clear them at all, resetting the adaptive stratergy memory (which is what Bob is trying to do in this case) does not take as long.

Bootiful - thanks mate, I didn't read above .. sorry.

Just went out the Road to give mine a road test after cleaning MAF and on Petrol it went like the clappers whereas before it felt like it was starving for fuel when you gave it to her. Seems to run better on Gas also.

Tank is having a rest in the garage with the battery disconnected after cleaning the MAF ... If that doesn't sort it, off to Repco I go to get a coolant temp sensor ... still baffled if it is that as to why two would go in the space of four months, but better that than possible alternatives!!! Fingers crossed!!

Tomorrow morning will be the final test after leaving it get dead cold overnight, but put the MAF back in, and reconnected the battery after about 3 hours (as I needed to go out) and it started first pop and purred like a kitten. Here's to hoping!!!

I hope it works as well as it did for me

Success!!! Well, I'll be a monkeys uncle. There was evidence of a bit of powdery dirt in there (smallest of specks) but obviously enough to cause issue ... started and idled like a dream ... I'm starting to think the MAF is something that should be taken out and cleaned after every reasonably muddy or dusty trip, and for the effort it takes, I think I'll just do it to keep it humming as long as possible - last thing I need is things going kaputsky on a petrol engine nearing 275000 klms ... would mean I get that new engine sooner rather than later though ... Hmmm ... Wonder if I should tell the missus it "really is on the way out dear" ... "you think we should just bite the bullet and book it in for the LS1?" ... lol

hey big rig , i can just see your missus looking over your shoulder as your typing with a rolling pin in her hand ...lol
