I bought the injectors from Mike at cruzing performance and put them in today. 2 seconds after its running I get a SES light. It's running really rough and hestitates when given gas. It smells like it's running really rich. I first tried running it with the stock chip and then switched it out witht my performance resource chip, neither solved the problem. Should I turn the Fuel pressure down or up? It's at 48 right now. Any help out there is appreciated.

Did you check the codes?

 

No, Not sure how to unless I take it to a garage.

 

You can display your codes by putting the computer in diagnostic mode. To do this you will need a very hitech piece of equipment... a paper clip (or anything that can jumper 2 pins on the ALDL connector under the dash). They sell a little key-like deal at AutoZone for about a $1 if you really want to get fancy. With the key off, insert your "diagnostic tool" between pins A&B on the ALDL (diagnostic) connector. These are the 2 upper righthand pins. Then turn the key to the 'on' position (don't crank it). This will put the ECM into diagnostic mode. The SES light should start to flash. It will 1st flash a code 12 indicating the ECM is in diagnostic mode. The light will flash 1 time, then a short pause, then flash twice followed by a slightly longer pause. Get it, 1 flash, 2 flashes = 12? This will repeat 3 times, then a longer pause. Then any trouble codes stored in the ECM memory will flash. Each code stored will flash 3 times, followed by a pause, then the next code will flash. After all codes have flashed, the sequence will repeat itself until the key is turned off. Have a pencil and paper ready to write doen the number of flashes.

 

Great thanks iroc

 

Sounds like another victim of leaky Accel 23# injectors to me. I had two of them to wash the cylinders brand new. Is your fuel pressure holding?

Well the pressure is staying steady at 48psi and the Code I'm getting is 33.

 

Code 33: High Voltage (low Vacuum) at Mass Air Flow Sensor (or Map Sensor). Ok, what next?

 

Sounds like you got a vacuum leak. Make sure you didn't forget any vac lines, and that all the gaskets are sealing well.
