AA active processor+UR downpipes:first cel

kompey · 07-02-2008, 02:43 AM

I've install the active processor for about 4 months and no problem.
Last week I install UR downpipes and the O2 sims and they work without problems.
On sunday I've also a track day and no issue.
Last night,after a little acceleration,the half engine check light appear!
I turn off the car and after restart.
Ceck disappear....I try to accelerate(1st-2-nd-3rd gear) and work perfectly.
I dont't understand what can be happened,have you idea???
Fuel level was very low.....
thanks

Do you have access to a scan tool to read the fault codes, this would be a good starting point for diagnosis
