alright i went and bought the OBD module to read the trouble codes and heres the results: air to fuel ratio to lean/rich, that would explain the engine stutter upon opening up the throttle how do i adjust that? if i can </P>


the second is misfire perhaps my engine timing is off? when i removed the belt to take off the alternator maybe i messed my timing?</P>


the third is EGR vacuum solenoid fault that is relatively easy to remedy however the other two are tricky i suppose the timing really isnt too hard just dont wanna buy timing set and the air to fuel ratio i have no idea how to remedy that and that is the biggest problem i am having i do think though that possibly the EGR solenoid has something to do with that (Exhaust Gas Recirculation) </P>


any ideas? maldavosta i know you wouldhave some input you seem pretty knowledgeable or anyone please help.<IMG src=smileys/smiley5.gif border="0"></P>

Timing i'snt gonna change by taking off the alternator belt. No accessory belt ever drives the cam gear. All your problems could be caused by your EGR system. I would fix that, then clean / replace your plugs, then unhook your battery for 15 minutes to reset the computer. See if that fixes your problem.

i think you are right and sorry for mispelling your handle <IMG src=smileys/smiley2.gif border="0"></P>


however troubleshooting the EGR will be simple until it comes to checking for leaks along the metal tube that runs down the back of the engine anyway i got my chilton manual out and its pretty resourceful</P>


lol also i might add that it just backfired bout 15 minutes ago hopefully the EGR fault will fix this.</P>

If that was leaking you would hear it. By the way I love roush mustangs, I hope you find your problem.
