Car: 2010 Jaguar XK 5.0L Convertible; Just put a new Battery in last month: Duralast Platinum H8-AGM; Group Size 49/Deep Cycle Capability:
Cold Cranking Amps (CCA): 900 A (A lot of people go right to the battery if something happens)

I know there are many threads on these P030x Missfire Codes, (Iv'e read tons of them) but this one is different. I took a short 18 mile drive today, just got new Michelin Tires yesterday, all the way around. With 4 new TPMS sensors. The car runs great!

The drive started out great, NO TPMS warnings (That's Fixed) and NO engine light. Car is clear for the first time in a while. I also changed out all 4 Speed Sensors this morning. This can't be something wrong with the Speed sensors I put in, can it?

As I was just getting back to my house, I stopped at a stop sign and the car would not idle, it still ran but was rough and went immediately into LIMP mode and I limped home about 4 blocks.

DTC Errors using my scan tool: P0302, P0304, P0306 & P0300. That's the entire LEFT side of the engine. I'm scared!

 

Can I ask why you replaced the wheel sensors?

I had a P0500 error.

 

If you delete all the left-bank misfire codes, does the engine run OK and how long does it take for the misfires to reappear?
