Hi, a week ago I was cruising about 45 mph when all of a sudden loss of power and car stuttering. I limped the car home at 5mph any gas input causes the car to stutter.

CEL shows p1354 and p0300

I changed the passenger side ocv as indicated by the CEL. But symptoms are still present (rough idle, loud knocking/ticking sound)

CEL now only shows misfire codes.

I have checked oil, all vacuum lines and maf. But am at a loss. I checked forums and YouTube for people with the same codes, but none persist like mines.

Curious if anyone has any inputs on other things I can try or check.

thank you!

 

Here’s a video of after I changed the solenoid

I'd check the timing belt. A skipped timing or a stretched timing belt often throws P1354 and P0300 together.

 

will do. I’ve exhausted everything else. Thank you.

 

did that fix your problem?

 

I haven’t had a chance to open up the timing belt covers yet. But I suspect the water pump froze and car jumped timing and bent some valves.

will update once I open it up.

 

Update. I did a compression test, all cylinders on driver side are normal and in 200 range. However on passenger side, all are only at 50ishpsi.

I removed timing covers, and on the passenger side the timing is off by 5 teeth and about a tooth on driver side.

The belt looks in fine, no signs of broken teeth and the tension is tight. Not sure how it could have jumped.

should I retime it and see if it fixes compression or is the bad compression already a sign of valve/ required head work?

 

With the cam and valves out of time I think you have head/valve work in your future, unfortunately.

 

If I am not wrong the marks on the belt are only there for installation, once they have been rotated the marks wont line up anymore anyway.

I would be suspicious of the belt jumping if everything looks fine but loss of compression on one bank is strange, you are ensuring at you are a TDC for the test?

 

I assume the timing marks for the other cam and crank are at their correct positions relative to the marks on the engine? If they are then you likely killed that engine

 

Yes they are
