Misfire

[dpfarr]

I had a minute to read about flashing CEL this morning and seems like it corresponds with how my car was running this morning. I haven’t had any time since getting to work besides now sitting w a cup of coffee. If anyone can contribute thoughts to this while I’m working, I would be VERY appreciative.

2020 edelbrock w delicious flex fuel.

I got off the road asap and turned off my car. Popped hood and you know checked oil, fine. Noticed a wet injector seal. There was a tiny bit of oil around my filter catch. I assumed I cleaned that out last time I changed my oil. I don’t know if there is any correlation to this.

Started it back up to check if there was any visible fuel escaping that DPI, and nothing. No CEL upon restart. CEL came back (not flashing) with a persistent SLIP indicator.

I have ECUTEK, so my move when I get a chance is to check fuel pressure? Going to order a new set of seals today. What other systems should I look at?

Thanks guys!

start with reading the cel code and maybe do a log with ecutek

PO302 Cyl 2 misfire

P219A O2 sensors a/f ratio imbalance

If I’m correct, cylinder 2 is driver’s side front? Same DI that showed leaking on the fuel rail injector interface seal.

I’m going to start there and replace all my DI seals. I have deatchswerks injectors and wonder if there’s preferable material for seals opposed to OE?
