What's causing the injectors to flood cyl after crossed jumper cables


You fired the electronic's in the vehicle , cost to much to change everything . You could take it to a qualified repair shop , cost an arm an a leg . Replacing control modules usually need progamming . I have seen this first hand , everything on the vehicle is electronic , instrument cluster , engine computer , body computer , ABS , air bags etc..... You could be chasing gremlins for a long time .

My 1984 camaro z28 keeps flooding. when i turn off the ignition key, the fuel keeps pouring fuel into the carb.


possibly a malfunction in the computer that controls the 1984 camaros carb would close the carburetor completely, cutting off the fuel supply or leaving the carburetor completely open, flooding the engine and causing it to stall or flodding the engine at shut off

I have 3 ipc codes what does ipc stand for 98 cadillac eldorado


IPC stands for Instrument panel control, here is a typical code repair flow chart, this is for example only and has nothing to do with your car..
P083 = 24x signal high.

P107 = Instrument panel control )IPC) to computer (PCM) data problem.

P137 = Loss of Automatic braking system (ABS) to Traction control system (TCS).

What you need to do is CLEAR all these codes from the computer and see which ones return.

Perform this test.

1. Ignition key ON. Engine OFF.

2. Simultaneously push and hold the OFF and WARMER (^) buttons on your climate control panel for 3 seconds and release them.

3. Diagnostic codes such as above will appear with the word HISTORY or CURRENT for each code.

4. The codes will stop when you see PCM?

5. Push and release the HI(^) button and you will see PCM DATA?

6. Push and release the LO(v) button and you will see PCM DATA?

7. Continue to push and release the LO (v) button until you see PCM CLEAR CODES?

8. Push and release the HI(^) button until you see PCM CODES CLEAR.

9. Turn OFF the ignition and wait 3 minutes and try and start the car. If the car starts and the light comes back ON, Turn OFF the car and repeat steps 1 thru 3 and let me know what codes you get and if they are HISTORY or CURRENT.

10. When you see PCM?, Turn OFF ignition key.

11. Let me know what codes you get and if they are HISTORY or CURRENT.



---------- FOLLOW-UP ----------

QUESTION: this is what happen when it did what you told me what to do.
P047 History,P107 History,No IPC Code, P83 History,P137 History, A047 Current, No Sir Codes, T072 History,No Russ, PCM?

2. Simultaneously push and hold the OFF and WARMER (^) buttons on your climate control panel for 3 seconds and release them.

3. Diagnostic codes such as above will appear with the word HISTORY or CURRENT for each code.

4. The codes will stop when you see PCM?

5. Push and release the HI(^) button and you will see PCM DATA?

6. Push and release the LO(v) button and you will see PCM DATA?

7. Continue to push and release the LO (v) button until you see PCM CLEAR CODES?

8. Push and release the HI(^) button until you see PCM CODES CLEAR. WAIT 3 seconds and then proceed to 9.

9. Turn OFF the ignition and wait 3 minutes and try and start the car. If the car starts and the light comes back ON, Turn OFF the car and repeat steps 1 thru 3 and let me know what codes you get and if they are HISTORY or CURRENT.

10. When you see PCM?, Turn OFF ignition key.
