My 98 LS400 started running rough with the p1346 code coming up.The timing belt was just done 3700 miles ago. Then the p1349 code came up? Any help would be appreciated!

 

sounds like whoever did the timing belt did it wrong, you seem to be off a tooth.

take it back and get it fixed, and be thankfully that it's only one tooth, as any more and you'd need a new motor.

 

Thanks I was not sure what the situation was. It's back in the shop that did the work. Luckily it is covered under warranty.

 

its not about warrantee it's a matter of doing the job correctly. you paid for a job to be done, the shop is on the hook warrantee or not to do it right or give you your money back.

 

The shop is telling me it was a crank position sensor that got moisture on it due to inspection cover/plug being off? Anyone think this is plausible?

 

it's possible, but if it was fine before then THEY damaged it.

 

Strangely enough the problem turns out to be the oil control valve on bank one! I pulled them both and cleaned them with the help from this site. The car ran great..... For ten miles or so then the check engine light came back on and the car ran really rough. This all started after a very hard braking situation. Thanks for the help!

 

Finally got my car back! It's running great,wasn't to bad. The oil control valves replaced and oil /filter change. Now just need to get new paint.
