the timing has been set the head is back together but the motor still doesn't idle like it used to what else could be wrong ??
Have you done a compression test?
yeah compression is between 175 and 180 in all four cylinders.
If the compression is good, i would recheck the cam timing and look for any possible vacuum leaks.
check your chain make sure it isnt stretched.
the check engine light came back on today. another multiple mis-fire code. this is killing me. my little jbody just isn't what it used to be
could be bad plugs wires coils on the misfire
when you blew a valve did it make contact with the spark plug if so it could be damaged
JBO since July 30, 2001
plugs are new. when it idles it jumps from 600 to 1000 rpms then it'll run smooth for a few seconds then it'll jump around again. when it first happened a few weeks back it would take a few turns of the key to start the car. but when i had the valve work done it started fine. today it took a few turns to start it.
