Question about 1999 Buick Regal
I need help i just instulled a used radiator, after i got it in and hooked up i started the car and it gave me a code p0301 p0201 and p0443, well i went to the junk yard and got a coil for the missfire plug 1 but now i still have a circut problem on the injector no.1 and to top it off i have a purge control valve circut malfu. now when i did the radiator i hook the battery positive post and with my wrench shorted the coil housing so could that be the problem or when i removed the ecm would that have caused the problem or does it seem that it has somthing to do with it i have a computor checker to read the codes after changing the coil i only have code p0201 and p0443 and the car is running rought at idle
The problem to code in the car could any one this
P0201 Injector Valve 1 Voltage High C-20
P0201 Injector Valve 1 Voltage Low C-20
P0201 Injector Valve 1 Open Circuit C-20
and for the code is P0443:
P0443 Fuel Tank Ventilation Valve Voltage High C-29
P0443 Fuel Tank Ventilation Valve Voltage Low C-29
