Check fuel pressure. Mine did this before fuel pump went out. You would be driving down the interstate and mash on the accelerator pedal and not speed up. After a mile or so down the road it would speed up. A few days later no start no fuel.

My truck sputters when i hit rough roads and when i press the gas pedal fast it hesitates


The cause of your Ford Ranger hesitating while pressing the gas pedal can be the fuel filter, change it first since its the cheapest, next would be bad spark plug boots cracked, or spark plug gaps to wide, then lastly dirty fuel injectors.-------------------------------------------autel ds708

Did tune up on my 91 ford f150 302 5.0L V8 4x4 pick up which included s[ark plugs and wires, cap and rotor, oil change, new oil and air filters...now it is riding rougher and worse gas mileage than before?...


did you properly "gap" the spark plugs? many spark plugs have to have the ends properly "gapped" before installation, by using a "gapping" tool/wheel to properly space the arc gap to the correct distance.

if the plugs were properly gapped, or already came pre-gapped out of the box for your specific vehicle, then you may have air getting into the cylinders around the spark plugs. were you careful to properly tighten the spark plugs straightly into place, or is there a chance that you left one loose, or, even worse, cross-threaded one of the spark plugs?

Misfiring after replacement of spark plugs and wires


If it wasn't misfiring before. Make sure you have the proper gap on the spark plugs. Make sure you have the wires connected in the correct order. If you have the old wires, you may want to end up trying those one at a time to make sure you don't have a defect wire either.
Thank you,

My 98 Toyota Camry V6 LE has 120,000 miles on it and runs great. However, lately I have noticed it sputters ever so slightly on the highway. right about 60 MPH. If coasting or accelerating it is fine. ...


Being that you have a 1998 Toyota Camry, these cars are fuel injected and shouldnt need the gas pedal depressed to feed fuel to your engine. It's possible you may have a dirty fuel pump or dirty injectors. Here are some possible steps (cheapest in $) so follow these in order to spend less money.
- Run some Lucas Fuel System Cleaner (green cap bottle), do two treatments of that in your gas tank and see if that makes a difference. Dirty lines and clogged injectors are caused by cheap gas and or constantly running on Empty thus allowing fuel pump to pick up sediment from bottom of gas tank.
- Sputtering could also be worn spark plugs (too big of a gap) and or faulty spark plug wires or both.
-Timing chain issues usually occur if you hear a constant vibration near the top of the engine.
-Transmission issues would be having trouble putting the car in certain gears, or the transmission stick does not sit in gear properly (slippage).

Just some suggestions that may help with your problem.

I change the spark plug and after starte to shake ann act weir and check engine light came on


Did you gap the spark plugs, or did any of the spark plug wires get damage while removing them, or did a spark plug wire get crossed,the engine light is most likely a cylinder misfire, I would check or replace spark plug wire's.

My Madza died while driving down th highway, felt


If you dont have much money, guessing what parts to change gets expensive. First, you need to verify if it has fuel pressure and spark, that will lead you in the direction to start looking for the problem. Pull 1 spark plug wire off and see if it will jump a 1/2" gap, If so, thats good. If no spark, make sure the cam is turning, you may have a broken timing belt.

2004 Grand Am acts like it's out of gas when it's not.


It almost sounds like you are losing spark at times, and not fuel. i guess the cheapest place to start is to change plugs and wires. Pay close attention to the gap on the plugs. Another thing could be the idle air control valve, or water in your fuel.

Car stopped as I left highway.


first you need to see if fuel pump is actually coming on when you turn key on.should be able to hear pump come on for a few seconds when key is turned on.if you do not hear it try to find the pump connector and use test light to see if it is getting proper voltage.most alwyas have 4 wires.look for a grey or purple wire.
