GMC SIERRA ENGINE PROBLEM

1995 GMC Sierra • 18,000 miles

Have been having a rough idle problem checked it out with my tester and come back code 35 iac, so I changed the iac a bit better but still not solved, you can actually smell the fuel what next.

What is litre size of engine? Is the code still present?

The 4.3L engine shows to have the spider fuel system, that system is noted for problems. The 5.0L engine shows to be tbi fuel injection. With tbi you can see the fuel injectors. With everything off, are the fuel injectors leaking?

Did you clean the throttle-body?
