well, the other day i was going about my business driving normally and then my car started to bog or not feel as smooth, and then throttle response changed into weird w/ the CEL activating. The problem went away and then last night it was worst cuz i could not go above 6000rpm. I had a shop check it out today and it read that my Throttle Positioning Sensor is bad. I have a CAI and a B-pipe. I know that sensors like that are covered under warranty So How Should i approach acura about it??? The TPS is expensive to purchase. Any suggestions would be really helpful.
