Need help w/ Codes (car runs bad)

[Rains]

Well, car seems to bogg down when i get on it a litle bit sometimes, like too much fuel...

i'm throwing codes 18/99

loss of TACH signal to ECA

ECA has not learned to control ening idle speed or electronic Pressure control solenoid failure.....


Anyone have any ideas???

HAve you cleared the codes ran it then checked again? Those codes may be old...
Anyway the tach signal is where I'd be worried...
The # 18 could be a dirty IAC/or TB. Clean those parts reset your idle & check for vac leaks...

Code 18 from the computer memory (KOEO) is likely to be a failing TFI or hall effect sensor (magnetic pickup) in the distributor.

Does anyone know if this would cause my stock tach not to work? I'm getting a code 18 as well and have not been able to get the tach to work and could use some help. I also heard that this could cause the car to run rich which my car is doing. Thanks
