 Subject: 94 5.2 wont idle steady
IP: Logged
Message:
I blew a trans line which threw oil all over the
engine compartment. Truck started running rough.
Figured ok, the coil is soaked in oil. Fixed the
line, cleaned up the oil but the truck still won't
idle or run right. RPM's range from 200-800, foot
off the throttle. Feels like it's missing till
about 3000 rpm, and seems to clear up at that
point. Coil tests good, new plugs, wires, cap,
rotor and pickup in the distributor. Cleaned up
all the splices as well, no change. Then we
noticed that with an inline spark tester, the
spark goes away for a few seconds. Tested this on
3 different plugs. Same result on all of them,
spark goes away, RPM drops, spark comes back RPM
races up to about 800 RPM and levels off until it
happens again. The PCM did get some trans oil on
it. I have not pulled the plug off of that yet,
but it doesn't look wet around the PCM connector.
I will be checking that this morning. The oil on
the PCM seems to be below the main connector going
to it. Since the PCM controls the spark, and that
is intermittent, I'm thinking bad PCM. Any other
ideas? Maybe a bad crank position sensor?
