I would replace the coil pack. It has to be something in theplugs wires c pack or t pack. Something is causing it to cut at a certain rpm and igniton components oversee this most of the time.

yea ur right it does kind of sound like it hits rev limiter, but at 35-4000 rpm?

 

[Froyd79]

Its tough to nail these gremlins down. I t could lie in the ecu(lets hope not) But my buddys did it at5k every time al the time bad coil pack was diagnosed.

man i hope ur right my baby was running so good then this/ we thought it was a vacume leak but we couldnt find any leaks so we were stumped, tomarrow we will try the coil pack...

Sounds like what happened to my last car when the spark plugs got wet.

get out your manual and voltmeter and test your ignition system components don not go buy 8 dollar plugs 60 dollar wires and a 200 dollar coil pack when you can test for free. The ignitions system componants are very easy to test.

Just buying parts without actually testing anything is a great way to lose a ton of money. If that's what your after, go ahead, but personally I wouldn't do it that way.

Check your throttle position closed switch. I bet the wire is disconnected. Thats exactly what these cars do when it is.
