Car cranks but doesn’t start

[HDJ]

So I just sprayed about 5 squirts of liqui moly upper intake cleaner and tried starting it but it just cranks but doesn’t start. Please help.

Did you remove the intake to spray the Liqui Moly?
Is the MAF plug fully seated?

Yes I’ve got an otr so removed everything and maf is seated properly. Car has started but I’m getting error codes but no cel light. It drives beautifully and idles perfectly as well. I’ve disconnected battery for 15 mins let idle 3 mins then off and idle again 3 mins then off not sure why these codes are coming up no light. Tried clearing but still come up.

Try taking it for a drive, at least 30mins. Don't baby it, give it a bit!
Seems like it needs to relearn some of the throttle body parameters.

Did that for 5 mins and was perfect in fact drove better than before even idles really smooth now. I’ll drive it tomorrow then scan in afternoon hopefully all sensors would have reset.

Although not reflected in the app, those DTCs are known as "permanent" DTCs and can only be cleared by the ECU itself after driving through certain drive cycles.

Only pending or current DTCs can be cleared by a scanner / code reader.

How long would these take to clear they still show up today

Could take a couple of days as the ECU has to go through multiple drive cycles before it determines those problems are actually fixed.

I’ll wait a few days I guess but really hoping there isn’t something wrong.

Yeah. Either way report back
