Ok, car originally had p0301, asked tuner what he thought he suggested new injector seals, so I tore apart the front, removed the obviously destroyed oem seals, and got hurt. (Tore my bicep tendon at work it was a great time )


Two years goes buy car has been sitting waiting for me to put it back together after my surgery and time allowed.

Car is now back together with new overspeed seals and at load and cold start it throws a mean p0300 code now. Sputters and spits on any kind of load.

Things I have done so far,


Changed plugs newly gapped

Filled gas tank there was about a 1/4 tank of two year old gas that was treated with Stable.

Cleaned maf

Checked every vacuum hose I could find

Going to run a compression test tomorrow and take some logs (will post after)

Slightly stumped.

This is what I was thinking too, when I had a random code myself after doing seals it was because the injector harness wasn't seated properly on the one injector so it wasn't firing properly.

Going to for sure, I'm also going to recheck torque on injectors just for peace of mind.

took everything back off, checked the torque on the crows feet, fuel rail, intake etc. plugged everything in. Put everything back together. No code. But still has symptoms, stutter, shudder and sputter. Compression is good on my china tester it was 172-174 all 4 cyl.

took some logs posted a bunch 1st is idle others are driving.


I'm gonna pull it apart again and send the injectors out to clean them and test
