Post all code numbers.
P0330 random misfire, p1800 air-intake bias control solenoid valve, p0011 ivt control performance bank 1, p0138 o2 sensor bank 1 sensor 2, p0021 ivt control circuit fail bank 2
Have the codes read again. Then post those new numbers. AutoZone will do it for free. P0330 is not a misfire code! Do you have a misfire in the engine?
Sorry the code is p0300 but I think I am goin to go today and read it again just to see what comes up my dad thinks it had water damage n is just bugging out but I'm not so sure on that
Ok.
Any particular place to start cause so Manny sensors r goin off I do t know where to start
seek a complete diag from a good mech. not auto zone
What, no magic? Lmao.
yes i made a cust disappear today.lol
LOL! YOU GOT TO LET ME KNOW HOW TO DO THAT ONE!!
HAPPY THANKS GIVING!!!
