tps problem....need some advice

[ReXy5709]

i got a ls/v in my rex, wired obd1 with a chipped p28. it has 2500 rev launch, 4500 vtec and 9k rev limit. it threw cel 7 for the tps and wouldnt rev past 2500 rpm's but sometimes it would out of nowhere. like id be driving, try to rev up and it would only go to 2500 then a minute later id rev and it would rev all the way up. so i changed out the tps, the cel went away and it ran great. about 15 minutes later the cel came on again and the same problems occured. i unplugged the sensor and it ran great for a min but then the same things happened. i ran it all day today with the tps unplugged and sometimes it would rev up and sometimes it would only go to 2500 rpm's. it also does the same thing with a stock p28. any suggestions/advice would be greatly appreciated. txt or a reply on here is fine. 706 618 7686

Make sure you have it pinned correctly. If you just did the swap and it was dpfi, then you have to reverse some wires.
