Ok, so I went out and worked on the blaze. I got the egr valve off no problem, cleaned it out and put a new gasket on and installed it back. I took off the IAC Valve and noticed OIL or some COOLANT in the valve and also in the sensor where the harness connects to it. I cleaned the sensor and valve out with electrical cleaner and was hoping that everything would work since the CEL said my IAC was malfunctioning. So I put everything back on and the blazer goes more wack than what it was doing. I cranked it and it goes up to about 1500 rpm then chugs down to about 500-600 rpm for a couple seconds then goes skyrocketing to 2000 rpm and then goes a little higher to about 2300 rpm and it plants itself there. It doesn't move at 2300 rpm, it idles there. WHAT THE F man. Anybody have any suggestions? Sorry I'm a little pissed right now. It's my dd.

 

Not that this is the thread to ask for help, but it sounds like your IAC valve is gone. The oil that you saw was likely from the valve itself.

 

Yeah, sorry about that. I just posted it here because this is what I've been doing to my blazer all day. Trying to figure out why it's going haywire.

I'm going to try one more thing before buying parts. I've cleaned 2 out of the 3. The EGR, IAC. I'll try the TPS and hopefully it's that. If it is, whether I clean it tonight or tomorrow, I'll get on here and jump for joy LOL!

 

I looked at my blazer is thought to my self how awesome it is.

 

washed it, changed my oil, realized that my tie rods are on their way out......

after spending money on it, i still love it

 

Drove it to work. And on the way the catalytic convertor decided it wanted to start rattling like crazy. Guess it's time for a new one. No CEL yet but damn it's annoying.

Well i'll add that i tried to pull the cat to get the chunks out. Snapped 2 of the 3 studs for the muffler and couldn't get any of the cat-y pipe bolts out. so now i'm running with no muffler and i'm going to have to have a shop do it. I just don't feel like dealing with it anymore.

 

ouch i bet she is loud with no muffler =)
