My H22 is running rough I have no codes. The following items have been checked or replaced.
1) Replaced distributor cap,rotor and coil.
2) Replaced spark plugs and wires.
3) Checked Ohms on Injectors (good)
4) Replaced fuel filter.
5) Checked fuel pump pressures (good)
6) Checked IAC voltage found 1 pin had 12 volts the other only had 10 volts?
7) My EGR valve is blocked off had problems with that long time ago so I installed a blocking plate.
I'm starting the think my computer is bad. I have a P13 in it now but I also have P28 that I was going to use for my turbo setup that I didn't get around to do. Is it okay to swap computers. Or does anyone have any ideas before I swap computers.
