Ok, I am having a problem with hesitation in my Prelude. In gear under load, at half throttle or more under 2500 RPMs, it kind of bucks and hesitates. This problem only occurs from like 1500-2500 at half throttle or more. I just replaced my distributor cap and rotor and wires as well as my fuel filter. Any ideas what else it could be?

 

I also noticed a backfire today when I backed off quickly at like 3000.

 

Sensor problem Probably TPS (ECU Error code 7)

Retard the distributor 4' will help..
Clean TPS connector with Brake cleaner (non chlorinated)

reset ECU and drive ...

 

where is the TPS located?

 

this problem also only occurs when the car is fully warmed up, not when it is cold

 

Check ya fuel pump (check the fuse too), also if you got an adjustable fuel regulator, check your fuel pressure isnt stuffing or spitting otu different fuel pressures, if all else fails, check your igniter in your distributor, also the coil, and maybe the fuel injectors as a last resort.

 

It's on the firewall side of the throttle body right where the intake meets the throttle body. Good luck

 

Well, I went for the $2.19 fix on a whim with some Gumout Air Intake and Throttle Body Cleaner. I sprayed the whole can into my intake manifold and the hesitation now appears to be gone. I still plan on cleaning my TPS though. Thanks for the help guys.
