Engine flutters loudly at stop lights. Sounds normal when driving.

You should not drive a car if the check engine light comes on and you do not know what the problem is. In some cases the check engine light means a serious problem and I know could cost a lot of money to repair. Mine came on and cost $800 dollars to repair as I tried to drive it.

94 ford ranger 2.3 stnd

talk with an auto electrician as there are now many alternators that are controlled by the ECM ( voltage regulator is in the ECM) 14.5 volts -14.38 volts is good voltage control so the problem may not be the regulator at all problem could be a shorting diode in the circuit or other problems not connected to either the alternator or regulator such as wiring shorting out , bad connections etc may even be an ECM problem

91 ford explorer turns over , tries to start

The catalytic converter or muffler maybe plugged up. This is based on the engine getting fuel and fire to the plugs. I would remove the 02 sensor ahead of the cat. and see if truck will start, be aware if it does start it will run rough. When the cat or muffler get blocked off it puts back pressure on the engine and thus not allow fuel into the cyl. to fire.

How do I pull the heater core on a 1991 Ford Explorer XL?

Actually, it is pretty easy to do. remove the glove box assembly. the case cover is right there. remove the 2 heater hoses under the hood. remove the inside cover screws and the core unbolts and comes right out. It only pays 1.2 hours in a shop. And you don't have to mess with the A/C system.

How do I reattach the adjuster spring to the self adjuster pawl on a 1991 Ford Explorer XL rear drum brake?

Put the adjuster in last. That is how I do it. It should be no problem to spread the shoes far enough apart. Then adjust til it is a snug fit to get the drum back on.

How do I get the horn to work and rear defrost? Is it a fuse related problem?

The horn and rear defrost are on two different circuits. There will be a fuse for each. Most common problem on SUV,s for the rear defrost is a broken wire on the glass grid of the rear window. As for the horn,it could be caused by a bad horn/fuse/horn relay/horn pad/broken wiring. You need to disconnect the wire to the horn and use a test light to see if there is power at the horn when the horn button is pressed. If there is power, the horn is bad. If no power, any of the afore mentioned could be the problem

Main power panel for my windows,door locks 1991 ford explorer needs replaced. Guy says he fixed it and now the door locks work but the windows on the passenger still dont work. What do I need to do?"

Hi there, I'm AL the owner of Big As Auto Repair. First, make sure that the window are not locked out. There is a lock out on the drivers master switch that could be in the lock-out-mode. Push that switch and see if the other windows work. If they don't further diagnosis will be needed. If you need further assistance go to my website below. Have an awesome day! Auto Repair
