I have a 2000 CSVT with a 3L in it. We put the SVT cams in it, when we did the swap. I have put almost 10,000 miles on it and it's ran like a champ. In the past week, it's been sporadic. Sometimes I start it and it will be missing when cold, but clear up after getting up to temperature. Other times, it's just the opposite and will be fine cold, but starts acting up after it gets warm. While driving it, it don't really feel like a miss. It's more of a power loss, like the fuel or timing is being taken away. I've replaced the TPS, the mass air meter, the IAT sensor and the tps sensor plug. It's not helped a thing. My next options are, crank or camshaft sensors. The cel just showed a low range on the tps, but I've changed it and it didn't help. Any and all help is appreciated.
