SprintRE 13bT. Int going super super rich. Odd TPS readings
Just got a 6yr build on the road. Used to have a tuned E6K, but upgraded to the Sprint. Overall I am very happy, but after about 60 mile, a intermittent
problem arose. Problem was short lived, but came and went several times. ECU is dumping fuel on the motor. Wide-band pegged down to 10:1 (might have been lower) and even stalled a few time going down the highway. Seamed to correct itself then went back to going super rich.
Later, I got a laptop hooked up. TPS signal was all over the place while it was doing this, then suddenly TPS signal went back to normal, but still rich.
Laptop died before I could run a data log. Car is being prepped for a show, so no driving till monday.
What should I check besides TPS??
Correction map way off somewhere??
What could be going on here??? A flooded rotary is no fun.
Im using the supplied 13bT S5 Map that came with the ecu; Starts and idles very well. Haven't boosted yet, as I'm still shaking down the chassis. Any help is appreciated, thanks

If the raw readings from the TPS are all over the place in the datalog without the throttle being touched then you either have an electrical issue (TPS ground, TPS signal wire floating/intermittent) or a bad TPS.

Removed and remounted the sensor. Also checked and adjusted timing. Running great now.
But I still think a new TPS sensor is in order. Is there one that fits particularly well on the S5 engine?
I found a few GM ones that might work that run in the $60 range.
