Intermediate levers?

[LVP]

So, I've had the car since Tuesday. Part of the deal with my wife was I knew it leaked and I was going to take it to a shop to fix the trouble spots. I agreed to fix stuff down the road, but out of the gate, I negotiated a few big repairs done in one shot

So I fired it up tonight to drop if off at the shop. Temp was around -8C. Ran fine all day today, took a nice long drive with the kids, no issues. Tonight when I started it, the idle was a bit lumpy and when I started driving it was garbage. Felt like it was misfiring and running on 4 cylinders. I pulled off the highway, shut it off, restarted it and you wouldn't know it was the same car. Ran fine the next 1.5h. Weird thing was that it didn't throw a single light or anything on the dash.

It's getting the valve covers and valley pan gaskets done. Think it could be the levers? I'll have them check the date stamps posted in previous threads. This is an interesting one…..

Cheers.
