So i had the dreaded P1349 pop up right after i bought the car. I had the car sitting for a while but yesterday i decided to tackle a couple of things. The spark plugs and cleaning of the small solenoid filter and cleaning of the vvti solenoid itself.

After trying to get everything as clean as possible i re-installed the filter and solenoid. The car almost immediately started to run great and like a whole new car.

I then decided to drive it home and make sure all was good. Made it home without any issues. Car ran great on the highway...smooth as my others. I even went to the market a little later.

This morning i drove it to work...about 10-15 minutes of driving the rough idle came back and the car was missing under 1k once again. On the highway it was fine.

I ran to the shop and grabbed the code read and once again P1349 came back along with P0135 (o2 sensor i believe). Not sure if related but both came up.

So the leads me to ask. Could the solenoid itself be bad or are the 2 codes some how related?

I will order a new filter and possibly a new solenoid soon.

I had a similar issue with my "00 GS3. Started right after I changed the timing belt. Turns out the belt had jumped several teeth. I'd pull the upper timing belt cover and see if the marks on the two cams and the mark on the crank line up.

OP it sounds like you need a new vvt solenoid/oil control valve, i had this code a few years back and replacing the solenoid fixed it....just my 2 cents

I'd say that would cause the car to run like **** all the time but it doesnt.

Seems to be the culprit.

need a new vvt solenoid/oil control valve: I would defiantly try valve first.

same difference?

Yes they are the same thing just different names

Oddly enough, it would run perfectly for the first 10 to 20 minutes. Then, it would run like crap once the car was good and warmed up.
