Long story short, The other day I replaced my air filter, cleaned the pedals on my throttle body, cleaned my IAC and topped off all the fluids in my truck. It drove fine. the next morning I went to start her and it cranked over but wouldnt start. It sounded as if My battery was dead and their wasn't enough power to turn the motor over. also, I cleaned my iac because i have an erratic idle and it stalls for no apparent reason, and when i accelerate hard it hesitates for a moment. NEED HELP QUICK!

 

If it is cranking slow, check the battery. If you have another vehicle handy, put some jumper cables on it, and see what happens.

 

Its not, I hooked up my battery charger and put it on engine start, its just goingits not turning over.

 

I just went and bought a new duralast battery because i'm planning on getting subs soon and my battery wouldn't not manage. and sure enough it cranked right over. makes me wonder abt my charger... It still idles rough, and thoughts?

 

Whens the last time you did a good tune up, plugs, plug wires, cap(brass posts) and rotor. Check all vacuum lines. And read the the sticky about lower plenum gasket repair. How many miles on truck? Bad TPS can cause idle to surge 100 to 200 rpms every 30 seconds or so. Need more information and the really smart guys are probably sleeping now. Search rough idle and you'll find lot of info. Good luck!
