Engine running rough.

I seem to have mulitple problems, most of which I seemed to have fixed. However, the engine runs at like 80%(of it’s full potential) until it starts to heat up then it’s like the computer flips a switch and it runs great. As a matter of fact, when it’s running good I do not think it’s ever ran that good.

I had a code 43 on the computer and it is now gone by way of fuel filter replacement. I have also replaced the PCV valve, O2 sensor and set the timing.

As far as the ignition is concerned all of the replacable parts have been replaced.

Valves are adjusted?

Could be related with a temp sensor… since your car runs great only when hot…

Sorry i’m not much help!
