my car idles fine until my temp gets to about 125. the it starts making sounds in the exhaust like its missing. heres the best way i can describe it. just sound it out and excuse the crudeness.

mmmmmmduhmmmmmmduhmmmduhmmmmmmmduh

no the mmmm's represent a smooth idle. the duh's represent i kind of sputer in it. its eradic. sometimes the sputters are close together and sometimes its far apart. when my car is fully warmed up and after ive driven it for awhile, its a more frequent, steady sputter. it never dies and it doesn't miss when its driven. im trying to identify what going on and could really use some help.

if youve seen this posted before sorry. ive been asking around.

It might have something to do with the spark plug warming or something. Thats just my guess.

always check the fuel filter, its like the #1 problem of all vehicles, when it gets clogged your stuff runs horrible

its an 89 gt. my mods are very few. underdrive pulleys, moroso cai, and dynomax catback dumped.
i replaced the fuel filter less than 500 miles ago along with plugs,wires,cap,rotor.
i haven't pulled codes for awhile.

Could be ECT related. Pull the codes to be sure. If it was constantly missing at idle, you could have advanced your base timing too much.

update. i pulled some codes. heres what came up.

koeo (key on engine off)
21- coolant temp out of specified range
coolant temp sensor out of specified range

c (continuoss memory)
67- nuetral drive switch or circuit
air conditioner clutch switch circuit

r (running)
44- air management system inoperative
94- secondary air system inoperative

now there one more code that im not to sure what it is. im not sure if i got this from continuous memory or running.

(koeo,c,r) 87-fuel pump circuit
(c) 187-injector pulse width lower than expected.

now the code 87 can be picked up from all 3. code 187 can only be picked from continuous. i can't remember. ive always had code 67. after i let the car warm up i tryed testing it again. i got a pass. the whole test is really hazy. give me any advice possible please.
