Problems with 99 Yukon

[Redman7]

I have the poppet on number 1 stuck shut. I was going to have the whole injection system cleaned by a shop near me. Any opinions on this vs. replacement. My thinking is, if I'm going to remove that cover to get to the spider, I'm going to switch over to the mfi system and that costs $300 more than cleaning. Just thinking out loud here.

hmmm, all these things are something i might want to consider this summer - i'm gonna work on solving my warm hesitant starting issue.

I hear ya I got the same problem

Ditch the popppets!!! Get the upgraded spider.

Don't even waste your money cleaning them. Best thing I did to my Tahoe.

Whoa. Sounds like you narrowly avoided a full-on engine fire. Go buy a lottery ticket!!!

lol +1!

it kinda sucks tho. i was hoping this'd be the first problem i could tackle myself on my Yukon, but i get the feeling it's about my skills as a newbie and i should do some other general maintence first to get a good hand on it lol

it was acually easy to fix. I just pulled the hood to make it easy for me to get into the engine. but i did go with the upgraded spyder.

imagine how hard this would have been a few years ago without the internet at your side. Jump in there and take care of it. You will be done and driving around before you know it.

i will, once i order a repair manual or two. just haven't gotten around to it yet. after this month's bills are done i will.

i just thought of this though - how would dirty fuel injection or stuck poppets affect only warm starting for me? cuz i don't have anything else wrong with the engine, be it at idle, WOT, around town, etc...
