Got a 2000 4.3 that stumbles. Worse when cold but always there. Been through a leaking injector spider. Plugs, distributor and the rest. She has no more codes and I'm drained. Starting to question the EGR. It's clean and never had a code for it. Not even for a lean condition. HELP!!!

Clean the maf sensor if it isn't reason the proper air into the engine it will be compensating all the time and could cause the stumble. Use some cleaner and a soft toothbrush.

I've cleaned the t-body and IAC. Had a 96 with throttle sticking on cold start up. MAF looks clean but will try that thanks.
