My vehicle listed above, in the morning starts fast but does run bad after like 2 minutes. We do it three times and press the gas and it will run after the car is up to almost 210 temperature, then we drive it fine but by the next morning it’s doing the same thing.

This happens when the engine coolant temperature sensor goes out, but we should run the codes first. here is the location of the sensor just in case you want to change it out. You can get a code scanner from Amazon for about $20.00.

Here is a guide/video to show you how:

These are oxygen sensor, crankshaft relearn sensor and EVAP sensor codes, how long has the check engine light been on and did these codes come up all at once?

Okay, crankshaft sensor is on still in morning sounds like it wants to cut off once it’s warm runs good. We have to replace the condenser it had a leak, but we put stop leak for the moment.

Okay, lets service the throttle bore which can cause the problem as well.
