Tps


My Viper only goes up to like 8200 rpm and I'm going to check out the powervalves this summer, but if they are OK is the TPS a possible culprit ?
 
I had my idle hang up at 4000 rpm, at first a flick of the throttle would allow the idle to drop to normal, after a while that didn't work. The tps failed the voltage test, bought a new one and that fixed the idle hang.
Didn't notice any high speed issues.
