1999 Chevy Tahoe Problems

[XxBIGxTEXxX]

I replaced all of my ignition system with all new components. You'd think newer aftermarket components would last longer than OE, at least I did. Wrong, hah. Mine didnt throw any codes either.

When did you replace your cap and rotor?
Have you replaced your spider assembly?
Have you ever replaced your fuel pump?
Have you replaced your fuel filter?

I replaced wires, spark plugs, cap and rotor, and fuel filter like 2 weeks ago.. i replaced my spider injectors about 2 or 3 years and my fuel pump got replaced like 3 or 4 years ago..

Mine is jerking again. This time atleast 10 times harder. I can feel the whole truck shake when it does it. And from looking around on the internet who knows what it could be so Im just gonna get rid of it before something major goes wrong. Im tired of messing with it.

i think it would be best if you can get some recorded live data of engine running including cylinder misfire history.

Looks like youre going to have to go deeper. What Sun said.

If youre set on getting rid of it, thats cool. If not I'd recommend doing what sun said. I was having an ignition problem a few years ago, it would shut off randomly and would stall on start-up. I did my research but wanted a professionals opinion, I brought it to a stealer and they confirmed the problem.
