p0170 lean exhaust
as above fault code cleared it using opcom keeps coming back , what do i need fit to kill it z18xe lump, also anyway around the key pass code to reset the ecu ?
Cars in limp mode now and idleing ruff dropping to 751 rpm then back up to 853rpm any ideas ive no manfoild leaks all conections to o2 sesors are clean and good??
No air leaks on inlet side?
Is that the only code showing up? My car which has the same engine was showing that code and one for the rear o2 sensor, changed it and deleted the code and it never came back
Although the 02 sensors might look ok, they can Fail internally
is the lamda sensor switching? id check for air leaks around throttle body and any pipes leading to inlet manifold.
Checked all pipes on inlet side nothink being sucked back in ? how can i test the lamber sensor or what am i looking for on the opcom ?
Look for all the codes that show up, then post them in here so people can get a better idea of the problemOriginally Posted by crash_ndie
£5 says you have a cracked or leaking exhaust manifold, which is sucking O2 in.
i have right though on number 1 cylinder and is been like that for months and had no problems with it ??
Youve just answered your own question, change the mani then delete the codes, no good deleting the codes if you havent fixed the problem
