stumbling? loss of power?

[SHOman24v]

i had recently did a timing belt and waterpump on my sho, the question i have is now all of the sudden the car has a check enging light, the idle is very low sometimes, when the car is cold and i start the engine it has a horrible idle then gets smooth, i have loss of low end power, and the car died once at 65mph. is this a cam sensor? a CPS? im so stumped?

If you've got a check engine light, pull the codes, then you'll know what's wrong.

Agreed. Although the codes may not tell you exactly what the problem is, at lease it will give you a good idea on where to start looking and what the problems are related to. Pull the codes first then ask questions. As to your symptoms, it is possible that it could be related to MAF sensor, ACT sensor, or IAB valve. there are procedures on www.shotimes.com for cleaning. The codes procedure is also located there.
