Have codes PO118, PO108, PO303,PO300,P2074 and were fixed

Question

I have a 2006 dodge caravan that I have had a whole new cooling system put in and then a tune-up, oil pan gasket, MAP, coolant temp, and oil pressure sensors also throttle poisoner sensor put in and all codes still come up but every time we put on comp diff and same ones come up. my van Still has this hesitation(Bucking) and will stall and some times wont restart. The temp Gage will drop to cold the back and sometime say over heat but with in seconds drop to normal or cold. Can some one give me a suggestion on why this is still going

Answer 1

P0300 Random misfire

P0303 Misfire number 3 cylinder

P0123 Throttle position sensor high

P0113 Intake air temperature sensor high'

P0118 Engine coolant temperature sensor high

P2074 Manifold pressure/Throttle position correlation-high flow / vacuum leak

When you code P2074 the main cause is vacuum leaks, P2074 will shut down the engine, A vacuum leak will also cause random misfire, Its possible that the vacuum leak is near the number cylinder, The rest of the code state sensor high, sensor high mean the component is disconnected, So you need to check your connection if the connection are secured, The next is to check the ground wire, The ground is also capable of setting sensor circuit high, Also when a temperature gauge moves up and down, this can also point to a improper ground.
