2003 GT, had just replaced the fuel pump, cleaned injectors, new plugs and a couple coils(NGK coils) that were broken when swapping intake manifold. Car was running fine, sounded/felt very healthy. Then last week after a month or so of driving fine, I started it up, it fired right up and then the exhaust note changed like an electronic exhaust flap closed. AKA like it went a little quieter. Not the sound of the idle coming down after a cold start, but like the engine was trying to move through sand. Like lethargic. Then when driving has that same feeling as it is driving to drive through sand or uphill.
I have shit skills/knowledge when it comes to engine diagnosis so I am reaching out as I start to dig into it and asking for any suggestions or directions in which to test. When hooked up to a scanner that can monitor live data, there is no misfires, no codes except for the fact I have no cats, fuel pressure is high 30's.
