Mer opti Max problems

I have a 2007 that has started not wanting to plane off when the air temperature is above 85 to 92 and the sun hitting it just bogs down any suggestions?

I'd guess its a sensor issue. You'd need to either ohm test the sensors (specs are in the shop manual), or bring it to someone with a DDT scan tool as, your ECU will have the failure code )s) stored. I am assuming the engine runs good when its below 85 air temp?

Yes it runs great before it gets hot
