My car recently has been throwing Cel 1 and 43. im more concerned with the 43 than anything. im going to pull the injectors and soak them in cleaner to see if that might be the problem. btw my car has a new fuel filter. anybody got other suggestion to what might be causing this?

 

Do you have any vaccuum leaks? Is your FPR adjustable?

 

sometimes a bad o2 will cause a code 43, i believe

 

it is throwing a code 1 which is O2, but that sensor is relatively new. No i just have a FP Gauge thats it. My car sometime tends to start then die like its not gettin gas, but usually starts the next try or so.

 

Test the fuel pressure, it could be your FPR or maybe your pump.

 

my fp gauge has been reading different numbers lately, usually a 5-10 psi difference at idle. im cleanin the injectors tomarrow, if continues ill look into investing into a wally pump. i wished i had a wideband grr

 

check the voltage on the connectors sometime they don't spray enough fuel due to lack of voltage
