I have 05 ford five hundred with a 3.0 engine i just replaced all 6 plugs with motor craft platuim and coils 1 2 3. Now i have codes for missfire on 4 5 6 and codes bank 1 lean and bank 2 lean 1 2 3 are not missfiring and also code for p0300 any ideas pleas it stalls as soon as its in put in drive the car will not move and when gas pressed it stalls
Ok replaced upper and lower intake manifold gaskets. Cyl 5 lower intake gasket was missing. Now when i start the car it will not rev up past 1500 rpm in park and it bounces from 1500 to 500. I have no codes now so im confused. I put my scanner on it and real tps read 3.2 at idle and 13.7 at wide open and throttle acuator command was 1.9 atvidle to 7.8
Dumb question...did you disconnect batt, wait 5-10 mins, reconnect batt, turn key forward (but not start) to allow for throttle body to sweep and recalibrate?

Update. No more missfire.however after i did the trotlle relearn, codes p0171 and p0174 came up bank 1 system to lean and bank 2 system too lean. Brand new spark plugs all 6 ignition coils and brand new upper and lower intake seals. It idles normal but when ya press gas it will not go above 2000 rpm and drops to 500 and ack upo to 1500 and repeat. When at 1500 rpm i hear fast rappid poping in exhaust but not at idle. I red egr, mass or fuel pump but witch one can cause both the rpm dropage and the rappid pops?
