list so far
cleaned IAC -
cleaned and tested IAT- spec within range
new plug wires -PO
replaced MAS -PO I cleaned it as it was dirty - maybe it was not new but a junkyard one?
replaced TPS-PO Verified it is a at .97 at throttle closed and goes smoothly up to 4.9 volts
replaced Crank Sensors- PO -pulled connector and cleaned it spray cleaner
Replaced coil pack- PO
replaced O2 Sensors
replaced EGR purge Solenoid, verified held vacuum, verified click open when 12 volts applied, verified that wire harness is good from EGR connector to fender well connector.
Ran new vacuum lines for EGR Purge Solenoid
verified could see through cat - PO
replaced battery with optima redtop - PO- battery at 12.8 volts rest- charge 15 volts
Ran new grounds and cleaned grounds, bat to alt, bat to ECM ground, bat to frame, cleaned and redid battery connections
replaced Water temp -2 wire- PO
replaced fuel filter - PO
ran wires to neutral gear switch - verified that car will not start when in gear and clutch is in gear.
fuel pressure - KOEO - 39psi Engine running 30psi - 39psi - when motor stumbles did not lose fuel pressure. stayed at 30 psi
Vacuum is at 18in idle goes to 22 throttle off on road- goes down to 1-0in at full throttle.
hooked timing light to #1 light skips every once in a while only skips a little when the motor is dieing.
I probably need to verify all the things that the PO did are good.
KOEO codes 522 565 threw a 528 code run time error as I was messing with clutch switch when it was running.
when motor is in open loop it runs decent. as soon as it goes to closed loop with engine in the warm zone it does a stumble and dies every once in a while. Fuel pressure stayed at good pressure, voltage on dash gauge does not change when motor dies. As it does the bucking and stumbling thing - if you put it in clutch the motor will recover. As soon as you let out the clutch the motor starts to die, or starts bucking as if it is not getting fuel. or bad fuel.
I think I am down to the big things
EDIS
ECM
Wire harness
little things to do
clutch cutout switch
ignition switch?
pull wires and check them
pull plugs and check color
compression test
run seafoam through manifold
run seafoam through gas tank
