eliminate cold start injector

[jevan01]

:lol: can you eliminate the cold start injector on a 1985 corvette tpi by blocking the fuel line and will this affect the computer?

you can plug the rear fuel rail connection,remove the 9th cold start injector and plug the port it mounts to on the intake, it will result in it taking longer for the engine to start and on occasion a trouble code but no harm to the engine, BUT the smart route is to upgrade the CPU this eliminates the need for the 9th injector, speeds up the computer and makes the engine run better

the ECM that came in 1986-1989 TPI Fbody's and Vettes is a series 1227165 (165). The ALDL data rate in this model can supply diagnostic data at 8192 BAUD.
