I was told by a mechanic the car had the check engine light for something simple, that I could drive the car and it will remove itself. I've driven the car almost 1,000 miles after that and the car drives fine sure it doesn't sound good after drives so I got it checked by 2 mechanics after that and I was told I need a new motor. Is that really what I need because the car drive good no hesitation it gets to speed? Not sure what I should do, is it a simple fix or do I really need a new motor? Forgot to mention when starting the car, it has like a longer crank as in like a 5 second crank to start. The car doesn't only have those 2 codes but also a couple more p001885, P042000, and p224085.

Based on the information you've provided, it's difficult to definitively determine whether your vehicle needs a new engine or not without a thorough inspection and diagnostics. However, I can provide some guidance on the error codes you mentioned, which might help you understand the nature of the issues.

It seems there might be a misunderstanding with the codes you've provided as they don't follow the standard format. Based on my knowledge up to September 2021, standard diagnostic trouble codes (DTCs) begin with a "P" and are followed by a four-digit number.

From the codes you've mentioned, "P042000" appears to be a typographical error. It likely should be "P0420", which commonly points to an issue with the catalytic converter efficiency being below the threshold. This could be due to a bad catalytic converter, oxygen sensor, or a fuel mixture issue.

Unfortunately, the codes "p001885" and "p224085" do not correspond to standard OBD-II (On-Board Diagnostics) codes as of my training data's cutoff in 2021.

As for the long cranking time before the engine starts, this could be related to several issues like a failing fuel pump, a clogged fuel filter, problems with your spark plugs, or a weak battery.

Given the uncertainty around the codes and the symptoms you've described, I would recommend getting a third opinion from a reputable, certified mechanic. It's also essential to communicate clearly about these issues to ensure the mechanic understands all symptoms for a more accurate diagnosis.
