I have new spark plugs, coils, weirs fuel injectors, fuel filter fuel pump, I think my PCT is the problem, but im not sure i did a diagnostic test and pretty much every thing came up as good then bad then good o2 sensor MAF sensore coils, it also sad that it was running lean then rich and visa versa over and over again.

I think its the PCT because one day i started the car and the PCT was extremely hot i think i might have burnt the insides of it, wold replacing this part solve my problems?
