I installed a new throttle body, and the car ran great after no TPS sensor for a few months ( I bought the car without one) and I'm throwing a code 43 (fuel supply system). The CEL comes on at random and then the car starts to sputter and run like ***, but some of the time when the light isn't on the thing runs perfect... Guys, please help.

 

sell ur car n buy a mustang, they run better

 

dude, don't interrupt my post with useless ****... please.

The kicker here is that my girl has a 95 V6 and it runs like **** too lol so I'm lost in this whole situation. I sit here and browse these forums like a ****in mad man and still no solution.

 

When I had a 43, replaced m o2 sensor and it went away/

 

el oh el

 

likewise...
i even went as far as replacing my fuel filter
try those & let us kno how it goes!

 

thanks gentlemen, I'll see what I can do... I have 2 O2 sensors. How will I find out which is the bad?

 

By getting the code. If your OBD 2 you will have a series of numbers, 5 digits I believe. If your OBD1, you only have one sensor.

 

I don't know which Integra you have, but according to my OEM Service Manual for the DA series; CODE 43 is fuel supply system or O2 sensors.

If it's the fuel supply system, here is the troubleshooting guide.

Note: The sources of a symptom are ranked in the order they should be inspected starting with (1).

ROUGH IDLE
(1) fuel injectors
(2) contaminated fuel

POOR PERFORMANCE
*Misfire or Rough Running
(1) fuel injector
(2) contaminated fuel
(3) pressure regulator

*Fails Emission Test
(1) pressure regulator
(2) fuel injector

*Loss of Power
(1) fuel pump
(2) fuel filter
(3) fuel injector

FREQUENT STALLING
*While Warming Up
(1) pressure regulator

*After Warming Up
(1) pressure regulator

Good luck!

 

thanks a lot bro, it's a 94 LS... but those definitely help!
