My Jimmy has the 4.3L CPI. I think my injector spider is bad, but I want to get second opinions on it.
Symptoms:
SES Code P0113 (Intake Air Temp Sensor, High Input) --Replaced Sensor, but that didnt fix the problem...going to put it back on the modus on Monday.
Misfires and has a Sulfur smell, usually when left to warm up in the morning.
SES Light blinks up to about 2000rpm then goes solid. Begins blinking again at stop lights (Idle).
--------
In the last year and a half i have replaced distributor cap, rotor, plug wires, plugs, egr valve(with Kleen Screen to prevent further build up), IAT sensor.
I am asking for an opinion on this because it seems to only misfire when it's cold (below 32 degrees Fahrenheit), and that does not seem consistant with most CPI injector issues.
Any ideas?
