c20let running problem

[torquey]

Ive noticed past couple of weeks of driving my let nova its kangarooing badly. Ive got wideband installed and cold its showing 17.4 sometimes gets into high 16"s. When half way on temp guage its all over the place 16.1-13.7. Do these figures seem right? Ive changed the plugs as the last were knackered and black. Was thinking could it be a knackered afm? On boost its showing 11-12's! Anyone shed any light on it. Its not right. Its eds phase2. Checked for vac/ boost leaks found none. New cts.:thumb:

Wideband is inconclusive. Could be a missfire causing the lean AFR. Sounds ok under boost though.

Will swap afm and see if it makes any difference. Cheers for your input

As said - the AFR is showing you that the fuelling's all over the shop... AFM's my bet too - the let ones can be particularly troublesome....

Got a spare will try it and c.

Temp sensor or working to it?

[torquey]

New cts fitted wiring seems ok.

Tried another afm tonight. No better wideband all over the place. Dont know whats up.!

Check ur wiring at ur tps plug I had this problem and turned out my wires had broken, check my project thread out think I had pics of my broken wires

Did it one day just start happening? or was it slowly getting worse?

[torquey]

Will check the wiring to the tps its just started to get worse. It doesnt missfire runs spot on except the kangarooing which happens more when cold.
