Hi Guys N Gals

 

Ive got a problem with the zed and its really starting to pee me off now!

 

Its a twin turbo manual and i can only describe it as 'popping' basically when i start it in the morning and its cold it idles lumpy. When you walk round the back of the car - because of the after market exhaust you can here it irregular popping! like a miss fire! - and it revs high as well.

 

When you rev it it sounds beautiful. and when its warm everything seens ok!

 

Last week i changed the plugs, fuel filter, and air filters. I havnt done the throttle bodies yet - could this be the problem?

 

Thanks

Tom

Hi Tom,

 

My advice to you would be to clean the throttle bodies, then the IACV valve, then clean all the connectors you can get to. While you're doing all that, remove the negative connection on your battery to give the ecu time to reset.

also, check & clean the connectors on the PTU
