Need help from the SC masters
First Off this Is Chuck Carroll not Mark. We are working over at marks house.
Well after a bizzilion tests I still cannot figure out my miss.
Here is what it does: at idle it has a noticable miss that sounds like a really lumpy cam. when driving on the road it misses continuously with a couple hickups every once and a while. During a hickup the tach drops about 400-500 rpm they picks back up to running rpm. On the tachat idle the miss in barely noticable.
It will more than likely hickup under any acceleration but not on every acceleration.
Here is what I have done: changed plug wires
Changed DIS
Changed Coil
Cam and crank sensor are less than 10000 miles old so I am shying away for those.
I have also pulled the plug wires one at a time and noticed somewhat of a difference on all cylinders. cylinder 3 is the most unnoticable.
I cannot run a cyliner balance test with a scanner due to my codes. which I have no idea how to fix the codes.
Codes are :
KOER
1. 13 Cannot control RPM during ER self test low RPM check
2. 91 HEGO circuit indicates system lean left side
KOEO
1. 95 Fuel Pump secondary circuit failed
2. 85 Canister Purge Circuit failure
I have tryed to check the signal from the crank and cam sensor with a test light but every time I tap into the wires the engine dies. What is the correct way of doing this?
Could this be a bad Fuel injector?
It does not sound like to me due to the random hickups that kills the motor.
I am starting to think about the computer its self?
I have an EEC tuner on the car and I have loaded my file onto that a couple of time thinking the tuner is bad but no luck.
I do not thisnk it is a pinched gasket or blown head gasket because I have good vaccum and no coolant in the oil with no coolant missing in the Radiator.
I have every bolt on imaginable and a equivilet to a stage 1 motor
Thanks for the input
