Rough idle on cold start only
I've had this truck for 2 years. Once I had it
home I did a tune up on it plugs wires cap
rotor and oil change. After I did that I had a
rpm surge. After replacing multiple parts
multiple times this year I solved the rpm
bounce. New distributor came with a faulty
icm. Drove around for a year with faulty part.
Now my only problem is a rough idle at cold
start up only. If I hold rpm at 1500 and wait
for the idle change it will run smooth with out
my foot on the gas. Without my foot on the
peddle it sometimes wont even stay running.
I have replaced alot. Some more than once.
Most recent fuel pump/filter starter battery
full tune up cap and rotor included. Ignition
control module and idle air valve. I messed up
putting starter in hot wire didn't get hooked
up to holding connector on the frame and it
melted and arked causing alot of sensors to
go bad. I've triple checked for vacume leaks
leaks last year had new intake gaskets put on
and got throttle body cleaned up. I've done
alot of chasing my own tail. Went as far as
removing egr with a plate and blocking all
vacume lines. Only code I'm getting is 34
