Solution: Could be the isc control which is an electric valve solenoid that regulates air flow for idle. Make sure the fuel and air filter are clean. You could have a vacuum leak in the fuel emissions system that is requiring the system to lag behind while the engine struggles to generate vacuum pressure. Sometimes one or more fuel injectors will leak overnight. The engine cylinder or cylinders will have wasted fuel and it will foul the plugs until the excess is quickly burned off. You might try a can of SeaFoam cleaner and see if it helps. , Hi, a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

Goodluck! , with my accord, it was the fuel pump. my bro replaced it, an presto! , no..i also have an 85 gr. marquis with the 5.0 engine... i changed the starter solenoid located next to the battery on the passenger side firewall of the car.. if it clicks then its either the solenoid or the starter..those are hard to kill cars with good grounds..check the solenoid.. , have the alternator check out. A good alternator should give produce voltage 13.8v or 14.5v ,but not greater than 15 volts , The cylinder head gaskit is on it's way out! had this before! caused by water leeking into the cylider(s) and making the compresion come right up ! remember air /fuel mixture is compressable water is NOT! , my mercury grand marquise turns over but wont start what could it be. would a fuse keep it from starting?
