friday car running great .....slightly uneven idle at first but soon smoothed out ..sunday bang cough backfire ... running .rough as a badgers bum ...put my hand over the exhausts no pressure at all( slight pressure ) on the passenger side and full exhaust presure on drivers side..seems lik eteh complete bank has dropped ..dont want to run the engine as i dont want any bore wash im just pumping fuel in there ...immediate thoughts are the PTU is gone ..anyone any other thoughts or ideas ???

 

cheers zed guru's

Ptu tend to fail when hot, not just overnight. My guess is MAF

Have you checked for spark or anything

Could be an injector, check your terminals for corrosion

Check the intercooler boost hoses...drivers side cooler feeds the passenger side bank and visa versa.

cheers

 

have had to leave it in the garage as im on my way to kaz ..will do some fault finding when i get home ..looking for spark etc etc ...checking connections ....i think i have a mk2 ptu somewhere so i could always swap that

Possibly green deposits in the coil/injector connectors.

Steve, let me know how you get on when you have chance to look at it :)

 

Edit: What a useless post that was :wack:

 

I've had a PTU fail over the space of a couple days, with symptoms not seeming to be temperature related. I'd offer to pop up and diagnose it for you, but I'm not up that way any time soon :(

will do , its going to be 4 weesk before i can have alook at it ..im pretty sure its the PTU as its all 3 cylinders on the passenger bank that are not firing

supose the best thing to do during fault finding is dissconect the fuel pump ( remove fuse ) to stop dumping fuel in the bores but still give me power to get a spark

 

zeds...gotta love em :)

Maf wouldn't be restricted to just one bank that would affect all ......

good point Tony looks more and more like the PTU or one of the connectors off the PTU
