Help!!! Misfire during crank

[EddieBauerCruzin4.0]

Hi I Have a 2001 Ford explorer eddie bauer 4.0 sohc and its misfiring everytime i crank the truck to turn it on i feel the missfire mid crank like right while cranking it misfires it stops the engine for a second then keeps turning over and will turn on .sometimes it does not do it.and will start normal another thing ive felt is while in park idle seems low and jumpy but very light feeling i think its idling at 500 or just a bit more

Any Help Please?

Are you sure it's not a draggy starter?

If it's truly misfiring, then the cause might be the sparkplugs, wires, or possibly the coilpack. Start with the plug wires and make sure thay are all securely plugged in, both at the coil pack and the plug ends.

Ok ill check out the coilpack and plugwires tomorrow i was also wondering about the starter do u think a starter from a 97 4.0 ohv would fit my 2001 4.0 sohc ? I have my old 97 about to junk it but left it laying around for parts i no the starter is good on it

I had checked this yesterday and they were in the correct order thank you

Has the battery been tested, ALL connections checked, and scanned for stored trouble codes?

I have not scanned for codes but i will try to take it to autozone tomorrow even though i have no engine light on they always tell me they cant scan without engine light on ill give it a shot anyways but i did test the battery with load tester and came out to good

Regardless if there is a CEL or not, there may be stored DTC's in memory unless they were cleared.

If any, write down the p0 NUMBERS and post them.

Ok so finally changed the starter from my other explorer problem solved thanks for your help now i need to calmly track down my low jumpy idle on park

That's great, and thanks for the follow up! I'd start with the IAC valve.

Also clean the throttle body and MAF sensor with their specific cleaning sprays.

Low jumpy idle at park on a SOHC is either your IAC or intake gaskets, mine had the same issues and it was the gaskets.

When you accelerate is there suppose to be a loud suction sound around the iac?

 

[RandomNerd2000]

That could be either the air going past, or a vacuum leak, does your truck run better when warm?
