Here's the background:
--95 z28 129,000miles
--rough idle, stumble, surging etc...
--initial scan showed left block learn about 10 lower than right, with both below 128 ( about 110/120)
--swapped injectors, problem didn't move to other side
--replaced EGR valve
--just replaced spark plugs and wires.......here's the new dilemma. I was dumb enough to purchase cheap autolite wires, replaced driver's side, took car to shop to replace passenger side, wires didn't fit passenger side, shop installed NAPA wires on passenger side ONLY,
--now, my left block learn reads 108 at idle ( injector 3.5ms), and the right block learn is way up to 150 (injector 4.7ms).....O2's look normal ( actually the right never dipped below stays primarily above 150mv now, previously they looked completely normal).......very rough idle and acceleration..........could the difference in wires make this dramatic of a change ? Or could it be the EGR gasket leaking? I am going to install the NAPA wires on the driver's side tomorrow......Anyone have any ideas -- Joe, Injuneer ????
Thanks for any ideas, Bill
