First change the fuel filter it may be clogged second check for fuel pressure at the fuel rail which runs along the top of the motor, look for the cap to the access valve unscrew and press on the inside of valve like you would if you were going to deflate a bicycle tube to see if gas squirts out, be sure to wear safety glasses and only press momentarily and quickly and also do this check with the ignition key on with engine cool. If no gas squirts out the fuel pump is bad. If gas squirts out the problem is most likely not a fuel delivery issue however the professional way to check is to screw on a 60 psi rated fuel pressure gauge and check to see if a minimun of 30 psi is present as key is turn on if not replace fuel pump. That check was for fuel now you must ascertain whether you have a faulty ignition pull out a spark plug and inspect it the plug should be tan in color if it is black it is most likely an ignition issue depending on what year it is the problem could be a bad ignition module or bad coil, if the car has a distributor replace the cap and rotor first along with spark plug wires. if it has individual coils pullout the spark plugs and correlate the fouled or black plugs with the coil the plug is associated with replacing the coil for that plug. Diagnosis of the ignition system in the absence of certain test equipment can be a slow and monotonous undertaking requiring patience and perseverance, the last thing to replace in this cae would be the ignition control module and before replacing that check to be sure 12 volts is present at the plug to the distributor or coil.

How do I fix my F150 Ford from squeaking on the front driver side.

It's your universal joints. Your universal joints have become warn and what's happening is as you accelerate its moving and the loose universal joints are moving which is causing the noise. It occurs at low speeds because of a slight wobble as speed increases the wobble goes away and so does the noise. It's best to change the font and back at the same time you can find them at your local part store starting at $19.99 each. As for your front end lubricate it real good. Hope this was helpful.

Death wobble jeep

Then your done

All jeep vehicles have had the wobble thing for decades

Unless you waste money on professionals attempting to
find the reasons for the issues, the only way to resolve it,
is start taking the front suspension apart completely & find
something that is worn,basically go thru the entire front end
including the steering & then check out the rear suspension real good

Not likely your working on your own vehicle or paying anyone,
at least any one knowledgeable enough to resolve things

Try the web sites or forums that are jeep related

Keep in mind they are mostly kids that don't know what
they are asking or talking about.

I have a very bad wobble which seems to be coming from the rear end.I think my tires are just really bad and the belts have seperated,but I also need a break job.I bought car used and no history I have put...

You really need to check all 3 to verify problem but if you find the belts are bad in the tires I would change them first as the brakes are not engaged when you are going down the road just when you are stopping also if it is a bearing it is going to be noisy all of the time not just at certain speeds.

Guys my jeep liberty 2003 engine start shaking when i reach 45 mph but before that in seconds the transmission shift 3ed to 4th several times in rapid and than the shaking happens and i must step a side...

Google "***** wobble" common on big Dodge, Ford, Chevy, and things (like Jeep's) with bigger tires and lifts as miles go up. Yours is also likey a bad wheel balance . Have the wheels balanced and watch them spin as they balance them.

Jeep grand cherokee larado 1999 going above 50

sounds like it time to have the front end balljoints inspected. Only with an inspection will you get the proper results. Why guess, this is a safety issue.

Symtoms of a bad timimg chain/belt...but ran real

Problem is not solved but I did change the fuel filter, coil pack,ICM and have proper fuel pressure to the motor. Car starts but dies right away. I cant seem to find out if the fob on the key ring has something to do with stopping the motor. This fob says Radio Key by Secure Key with a number 35077 stamped on this thing.. Still trying to find out what this is and does it effect the cars ability to run
