O/T: 96 tahoe

[70cst10_05]

Howdy all,
I have a 96 Chevy tahoe w/ a 5.7 and last thursday it developed a heavy noticable loss in power and miss, so i went to a friends and put a computer on it and it came up with a "random misfire" on no. 1 cyl. and no. 4 cyl, so i put a cap and rotor on it and it helped a lot, but there is still a slight miss. i put new spark plugs in it friday, and the wires are only a couple months old.....any suggestions on what this might be?i had a mechanic tell me that the the 1 and 4 cylinders are on the same intake runner and the intake gasket might be leaking but it hasn't used any antifreeze. I myself thought it might be an injector problem or bad wires, i haven't had time to check the wires......sorry for the long post, and all help is appreciated.
thanks,
kevin

From what I've heard, those intake manifold gaskets are notorious for leaking. You said you haven't found any sign of a leak... check the oil to see if there is any gas in it. Good luck.

Thanks for your input, but it was a dirty injector....i put 3 bottles of injector cleaner in it and i was drivin around tonight and it cleared up......runs like a striped ape now.....

I have a '96 Tahoe too! Great car. I bought it about 4-years ago with 39,000 miles on it. Mine started running bad one time and it was the fuel pump. Very expensive to have fixed! The next thing was the EGR-Valve. Easy to fix but the part was expensive (> $200.00). Other than that, no problems. It has 75,000 miles now (not bad for an 8-year old car). I don't know how people afford the new ones. List price for an LT like mine is $ 47,000.00. Whew!
