Let me shoot u in the right direction I guarantee it's your coil pack a common problem on these it prob has a hairline crack in it wich in turn is getting your firing screwed up and it will affect the transmission into fluttering at those speeds try a new coil pack and u will see a huge difference in your van regards Chris

SOURCE: Replacing an intake manifold gasket on 1993 ford ranger 4.0

I've replaced several of these gasets and they were made that way.
It wouldn't hurt to call a different autoparts store and ask them if theirs are made that way.

most likely not the fuel filter- try plugs and wires... could be a number of things, if the vehicle runs fine while in park and doesnt hesitate, most likely is sprk plugs and wires or a transmission problem...

Po300 code possible fixes?


HI there:

Basically this means that the the car's computer has detected that not all of the engine's cylinders are firing properly.


A P0300 diagnostic code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why.


Symptoms may include:

the engine may be harder to start
the engine may stumble / stumble, and/or hesitate
other symptoms may also be present

A code P0300 may mean that one or more of the following has happened:
Faulty spark plugs or wires
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector(s)
Burned exhaust valve
Faulty catalytic converter(s)
Stuck/blocked EGR valve / passages
Faulty camshaft position sensor
Defective computer


Possible Solutions: If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.


If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.


Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

I have a 2006 Ford Freestar 48K miles, I just had an issue where my check engine light came on took it to AutoZone they put it on the machine it was a #2misfire got the spark plugs, wires and filter c


Find out if this air valve is considered an Emissions part. I would say it is not, but it depends on the effect on the emissions. If it is a covered part, the Emissions devices are Federally mandated to last a longer period of time and miles than the rest of the car.

The air valve is usually a different component than a throttle valve. The air valve is a part inside the air intake which changes the flow of air underneath the intake manifold. The throttle valve is a big flap on the top of the intake manifold which moves directly with the gas footpedal. The air valve operates automatically to change the air passages beneath the intake. The throttle valve changes the air opening from the air filter and is manually controlled by the footpeadal.

You might ask them if the engine has manifold "runners" and if it does, then that could be the problem. Ford had several problems with these runners. Also, I can't say if your design is a sandwich manifold, but the sandwich intake manifold had a gasket in the middle to join top and bottom and over time the gasket dissolved making a leak.

I would get a second opinion for this repair.

Check vacuum leaks , by spraying carburator cleaner around intake manifold gasket and vacuum hoses connections . See if engine picks up the idle speed while you doing it , and if it does , locate leak and fix it. Most common , intake manifold gasket brakes.

3.8L Engine hesitation when given gas, changed, plugs,wiring,dis cap,rotor,fuel fiter?


Try a TPS, throttle position sensor. It both advances the spark and increases fuel pressure when you push down on the pedal. If the TPS does not repair it, then use a water spray bottle around all the intake manifold seams while the engine is running.

If you have a intake manifold gasket leak the engine will pull in the water and change the RPM. An intake leak will throw off all the settings and cause hesitation.

I got code PO303 on my 2006 ford freestar i just want to know what i can expect it to cost to fix


A P0303 code is a cylinder #3 misfire code. Usally a tune up, of plugs and wires fixes the problem. Normal cost is about $5 dollars a spark plug, about $85 in spark plug wires and around $100 in labor. So around $200-250 for the tune up. Then you'll need them to clear the check engine light, which may cost a diagnostic fee. If you haven't done a tune up in a while that would be the place to start. The other problem it could be is a fuel injector or a cylinder compression problem but those are unlikely. Hope this helps.

Try the fuel filter. If you have had the plugs, wires changed it may be the fuel filter.
