Question about 2004 Chevrolet Tahoe
Have a 2002 tahoe with 84000 miles last year i noticed a rough idle in the morning when i started it the sevice engine soon light would flash but when started driving it went out and the truck would be running better but still had a hesitation at idle or sitting still.i changed plugs and wires and gapped plugs at the right specs.nothing worked.then i put a maf sensor on and thought it fixed it but the weather had just got warm and besides the little miss it was running better untill it just starting getting cold again now it started again finally i had the engine light stay on and got a code 0174 i put spark plug gappers on the oxygen sensors and cleared the code nothing again.just today i changed the plugs again and gapped them at the called for specs,there was a wet reddish yellow tinted substance on the first 2 plugs on the drivers side. once again still have the faint miss sounds like it could stall but dont. it seems 2 run a little smoother but the miss is still there. any suggestions would very much be appreciated. im out o f ideas only thing else i can think of is the intake plenum gaskets.
Need to pull plugs and crank over in morning and see if water blows out of any plug holes. Sounds like water in cyclender.
