Idle problem

[imfromthesouth1978]

Im sure this has been asked but can't find any post but I have a 95 suburban k1500 with 5.7 with low load rough running miss. When idling it runs fine but driving down the road with foot barley on gas just to hold the speed it has a miss but when you give it gas it smooths out...only does it driving down the road as I said with low load on the gas. Just did plugs, wire, cap and rotor tune up and it did not fix mt issue.....

Whats your fuel pressure like?

 

How is the spray pattern on the TBI injectors?? If they are dripping fuel, they need to be replaced.

 

I'd even smoke test for vacuum leaks as well.

Not sure of pressure but the pattern comes out in nice cone shape and ill try the smoke test this weekend checking  for vacuum...heck I didn't even think about that...thank you
