1999 gmc Sierra 1500 4.3 4x4
Has very small shudder at idle and only happens once in a while. All ignition and fuel and mostly everything in truck has been replaced in the last year. Fuel pump from dealer, fuel filter replaced last year, iac maf tps rotor cap cam sensor everything from quality parts. Thought it was a dirty filter since it’s been a while and I started the truck with no filter seemed to fix it but when decided to drive to auto parts store without filter shudder started up again. Happens only once in a while and acceleration has never been better. Really happy how it’s driving. No codes. Question is wouldnt a slight mis be noticeable at acceleration?
