Having problems with your 1997 Toyota 4Runner ?

Can't pass smog! OBD codes P0303 & P0306, what's my best bet?

\015 Cannot pass smog test due to OBD codes P0303 and P0306 on a 1007 Toyota 4Runner 3.4L V6 2WD. Changing spark plugs, wires, and coil have been recommended. I've also got one heely-coil, due to a spark plug literally shooting out! I'm not sure which cylinder that's on, but it's been there for about 4yrs. I really just want an honest opinion on the best track to getting my baby smogged! Thank you! Leah\015 Posted / edited by AnonymousUser on : 20-09-2021
