hesitating, bogging, 7 cyl like

homeroV8 · 05-11-2002, 02:48 PM

I installed BBk o/r and the car car was great; aftr 100 miles, the car started to idle terribly, and when accelerating it´s like it´s on 7 cylinder (just if had taken off a plug or wire).
I´m really worried cause I also hear some noise in the engine, resembling valve or lifters, coming from the driver side (just like solid lifters; very subtle, maybe I´m just hearing things...) .
Thanks a lot in advance.

Run an EEC test, I suspect bad 02's.

Thanks for the input,I sincerely hope you´re right!

I thought if the O2's reading went out of spec, the computer would just revert back to open loop mode...
I know for a fact that new O2's will help the idle and gas mileage though....

i think you might of said what is wrong with it..make sure that a plug wire isnt arcing..i bet one is..shorty equal legths are notorious for buring up wires left and right

woops ya said h-pipe..those only real way to get an accurate reading on a offroad h-pipe is to weld a metal playe directly behind the o2 boss..the backup of the cats is what heated up the 02s b4..now it is too free flowing..this cure works or you will run lean..

is running great again. As easy as that!
Thanks to all, anyway!
