surges/misses upon acceleration around 40mph, I replaced the EGR valve &
solenoid (already changed plugs, cap, distributor, wires Fuel filter) The car
had problems when I got it.
The car still has the same problem after I changed the egr valve & solenoid, I
visually checked the operation on the egr valve on the car (I have the Factory
Service Manual)and off, but when the car reaches the 3,000 rpm, the valve does
not open fully (as it does during the vacuum check)it has approx 1/4 of movement
& it jumps back & forth from close- opening 1/4 inch. I checked the vacuum going
in to the solenoid, no problem, but coming out from the solenoid to the egr, it
is very little & is unchanged even at 3,000 rpm. So I the then checked the
voltage to the solenoid & it jumps all over & I cannot get a stable reading at
any rpm, it jumps so much you cannot read it.
HELP! Is the PCM defective? I know it is supposed to control the voltage to the
solenoid, I unplugged the PCM & inspected the pins, then re-connectd the plugs,
still the same.
Thanks for all the help you can give me,
have the same problem?
