I HAVE A 85 TPI CORVETTE STD. I JUST PUT NEW FUEL PUMP ON IT NEW TPS AND FUEL FILTER NO IT SEEMS TO HAVE A LITTIL STUMBEL WHEN YOU PULL A HILL KEEPING THE THROTTEL IN ONE POSTION BUT WHEN YOU ACCELERATE IT GOES SMOOTH I HAVE A CODE 32 WICH SAYS THE EGR VALVE COULD THIS CAUSE THE PROBLEM . SHOULD THERE BE FUEL PREESURE ON THE RAIL VALVE WHEN ENGIN IS OFF I MEAN A LOT LIKE BLAST OUT WHEN U HIT THE VALVE NOT JUST OZZING LIKE NOW THANKS

 

32 is for EGR flow and that is measured by the ECM by looking at the O2 readings. When the car is commanded by the ECM to open the EGR valve, the ECM watches the O2 readings and if it doesn't see a change within so many milliseconds, it assumes the EGR is not opening. I have seen middle 80's cars set an EGR code with a stopped up fuel filter because the car is running a little lean. More than likely, the EGR code is not your problem but maybe a result of it. You might have ignition problems, wires, plugs, cap, even dirty injectors. There should be risidual pressure in the rail for at least 5 minutes, if there is not, you could have a leaking injector or the check valve in the fuel pump is bad. Good Luck [8D]

 

might check your o2 sensor too

 

OK WERE IS THE 02 SENSER I NEVER SEEN IT IN THE BOOK ?

 

drivers side of the y-pipe, just below the exhaust manifold. you'll have to jack the front of the car to get to it....just like everything else. if its been a while or if you cant remember the last time its been changed, might as well throw a new one in, less than $30

 

OK I WASENT SURE ITS NOT BEEN CHANGED FOREVER PROBLY SCINCE 1985 LOL I AM GOING TO CHANGE IT NOW SEE WHAT HAPPENS THANKS

 

Don't use a cheap one. Cheap one usually have a tendency to not switch from rich to lean and lean to rich quick enough and fuel economy suffers a little. Stay with A/C Delco. [8D]

 

well i replaced it it fixed the code error it had so much corrision on it i barly got it of the hole and plus i retimed the car it says 6 degrees btdc i put it there it dosent seem to accellerate as quick but seems like all the power is there at wot

 

glad u found the problem!!

ive got my timing set at 8 or 9 btdc. i try to use 89 or 93 octane gas to give me the best performance feel.
