Hi there,


I have 2001 Rodeo. I recently replaced right head and did full tune up. Since than i have check engine light on. I pull codes from OBD tester and I get P1312, P0300, and sometimes P0463, and P1311. I replaced all ignition coils, ignition module, MAP sensor, even I get used working ECU (two of them) and still the same. On moments there is no light on, and then as soon as I push on gas pedal light start flashing and then goes on stady, and flashing again and again...[img]smileys/smiley7.gif[/img]


Any idea what I should replaced next. I m open for any sugestions.


Please let me know if you ever had any problems like this one.


Thanks

 

I fix the problem.


Replaced new bosch platinum sparkplugs with oem denso double platinum (Denso PK16PR-P11) and everything is ok. No more CEL.

Glad you got it figured out. Without looking up the codes my first thought was intake manifold gasket. But yeah, you have to use specific plugs in ''00+ rodeos because of the ion sensing system.

Btw, a flashing cel means there is something wrong that could cause damage to the cat converter.
