I think its broken

so..so this evening on the way home (90 mile trip) I was dealing with a idiot in a fairly slow car...but was also accelerating hard and noticing it was taking me longer than usual...shifted outa 3rd at 6700rpm and went into 4th and noticed the car wasn't pulling at all......(but was still enough to put some nice distance on this guy)

so...the ride home the car was misfiring/running rough when I was going uphill...if i took the car into another gear it would be fine and I could accelerate...by the time I got home the car was running fine again and not misfiring under load

93 quad..253,XXX original miles....what should I look for....

My first check would be ignition module and ignition coils.

[93GTZguy]

what should I check with the iginition module and coils?

Sounds more like a faulty plug or plug boot to me. Pull your IDI cover, and check the ICM Module for cracks/heat stress. Then look at your plug boots and plugs. GL.

Im gonna bet plugs..but I left all my tools at work..so...I will have to postpone checking the problem until monday afternoon...I guess Ill be driving my gas guzzler to work for the next few days

Don't overlook the whole coil cover either.

[93GTZguy]
