Engine Performance problem
1995 GMC Jimmy 6 cyl Four Wheel Drive Automatic 163000 miles
I have a 95 GMC Jimmy 4.3 Vortec (CPI) 4x4 with 163k miles.
The RPMs rev between 500 and 1500. It almost feels like its choking and sometimes stalls at the bottom. It fires right back up every time. The idle spikes up and down and continues this nasty cycle. It gets better as the truck warms up.
Idle Air Control Valve
Tune up (Plugs/Wires/Cap/PCV/Rotor Button)
Several people have told me it needs a new Spider Injector. Is there anything else I can rule out or check before I invest the $300 for the injector?
Any info and advice is much appreciated! Thanks!
have the same problem?
