Engine misfire and backfire, UPDATE on last page
Im working on a 89 here and have run into a wall and can use some imput.
It starts but chugs and will barely stay running if you give it half throttle.
Here is what has been done thus far> Every sensor has been changed with known working ones including the coil,dis,computer, ignition switch,fuel pump relay,FPR. The car had about a qt. and a half extra oil, found out it was gas in the oil. Drained it out and replaced oil. its got to be getting good fuel. It has good spark on all plugs. Replaced the balancer,crank sensor= no change. Had the top half of the motor off to make shure all vacume lines and intakes were sealed. Car had even compression when checked. Took off the oil cap to make shure rockers were rocken, they were. No codes from scanner, gives me a {11 11} every time on KOEO and no stored codes. I pulled the wires off the maf , cam sensor, octane plug, spout connector nothing make a diffence.
Im just out of ideas unless it jumped timming but how can you tell untill you have the chain cover off? anyone have any ideas?
