the other day i was driving and my car started to act up.. when i give it some gas it feels like my car leans out and hesitates for a second then it takes off.. it also sounds like it miss fires here and there. i got a cel for map sensor , air intake temp.... i have a missing link, stock ecu and a fmu . iam only running 5 psi till i get a management and tuned. any ideas.. when i replaced the map sensor with a new one there was no change.. when i took out the missing link it pretty much ran fine. so my question is could the missing link go bad. or could the tps and map plugs have gotten swithed.. it first i thought i had a throttle body gasket leak.. the only thing i kno is that i need new spark plug wires.. thanks for ne help
