95 Talon Esi Missing

[l3igl3ang]

yeah my talon has a miss to it sometimes most the time it drives good then if i gas it and drive real fast like trying to get ahead of some one at a stop light or any thing then its starts missing real bad so far i have put good plug wires and new plugs on the car from when i bought it so that eliminates them two options so i have no other idea what it could be maybe a bad coil? maybe u guys will know.

o and if it was plugs then u think it would do it all the time and not just sometimes my check engine lights comes and and says it has a bad IAC which i changed and it still says my IAC is bad but other then that I'm stumped.

well i guess im going to take it to a auto shop today i was driveing it and it was missing really bad so i put new plugs in and still did it then all sundden im driveing and the rpms drops 2 0 like if them car just shut off then it would pop back up to 3000 rpms it did this quite a few times and its missing really bad any ideas ?

My car stumbles/misses when accelerating. Is there a fix?
This is usually poor ignition, caused by:

bad, incorrect, platinum or poorly gapped spark plugs
bad or loose plug wires
bad ignition coil
bad transistor pack
Try swapping each one out until you fix the problem. Testing the components may or may not reveal the problem; many people have had components (especially wires) test ok, but perform badly on the car. Plug wires may also be loose in the coil pack, although they may look fine.

Other possible causes include a bad battery connection (or bad battery), leading to poor power to the fuel pump; misaligned timing belt; excessively high airflow through the 1G MAS, leading to 'missed' counts; incorrect routing of the vacuum hoses on the throttle body (there was a mistake in a shop manual somewhere); decaying of the ECU capacitors (a must read - go here for details); worn camshaft lobes (normally only a possible problem on certain aftermarket parts called Web Cams); or (in at least one case) a broken thermostat.
