I changed the cap, plug and coil wires, fuel filter (dirty appeared to be from Ford on a 100K chasis). I was dumb not to look into that before putting it back together. Adding a new MAM and TB this week. I will then get it back to the Dyno late next week and let everybody know how she does. It already feels stronger except it no longer wants to idle when the chip is flipped to the street tune

I appreciate the reply's it really helps me in tracking down cause(s). Everything will be addressed and I will be looking into the clutch slipage.

Thanks

a dirty fuel filter can surely cause a huge loss in power. my 96 cobra ran like a diff car after simply changing it. haha. an if it is 100K old.. good god i dunno how ur car even runs. i hope u gett it all worked out!

If your car is a real Cobra it should have came with a 65mm TB from the factory

Car is a real Cobra (#4709) I bought it from a friend who was the original owner (bone stock down to air silencer when purchased).

I've read that the 93's had a 65mm but 94-95's had a 60mm. No idea why they went smaller with the more restrictive intake inlet. I checked several places and even measured mine before ordering another one.
