My friend is getting a code 43 on from his ECU. I looked it up on the Haynes book and it doesn't go up to 43. He is getting 4 long blinks and 3 short one's. He says that his car studders a bit on the highway and has a ruff idle at start up. On OBD1 code 43 has something to do with fuel delivery would it be the same for OBD0?

 

my buddy just had that code on his del sol
he took the O 2 sensor off
soaked it on seafoam for 15 minutes, installed it and it ran fine... i guess is too much **** in the sensor

 

So code 43 is the same for obd0?

 

There are only 16 codes on the obd0 pm6.. You probably have a code 4 and a code 3..

 

yeah , there is no long flash on the pm6
