91 Gt4 Rc Running To Fast

[tallguy-gt4]

hi there guys havent had any probs with me car since you guys helped some time ago.. but im having a sligh prob, when i start me car from cold it revs between 1700 to 2000 rpm, but when the temp gauge warms up it drops down to 1000rpm, any ideas what it could be, what should it run at when warm???????

also when driving hard sometimes between changing gears occasionly i get a small pop from the exhasut,

could this be over fueling?????

Check the throttle valve is closing fully and the cable is ok. Might be worth checking the timing too. Have you tried pulling any error codes or doing an ECU reset??

The popping is fairly normal GT4 behaviour. They do tend to over fuel somewhat.
