k, guys heres my little problem . i have a 91 eagle talon
that idles like ----. theres no codes ive checked for vaccum leaks, cleaned out the mass air flow sensor check the o2 sensor, im thinkling its the throttle postioning sensor but im not sure any help?

 

high idle, low idle, lumpy idle, varried idle? what do u mean by shitty.

 

lumpy in nuetral and low in gear

 

maybe you blown a head gasket. That's what happened to me and i'm experiencing the same problem you having. It can be many other things. Like your vac source is leaking. Check all your Vac lines. It can be leaking. check MAP sensor. ETC....

 

check the BISS. on the top of the TB there will be a screw going into it (possibly with a cap on it) that adjusts your throttle at idle...maybe the screw came loose (or out, i've heard of that happening) which will wreck your idle.
