Question about 1998 Ford Explorer

I have a 1997 Ford Explorer. It starts harder

I have a 1997 Ford Explorer. It starts harder than it should, sometimes will backfire when it starts, and a puff of blue smoke will come from under the hood. After it starts, it sounds like it wants to die. What are the possible problems?

The most likely cause is a "gunked-up" throttle body assembly. You can take care of this yourself with a spray can of throttle body cleaner (follow instructions on the can) if you're not afraid to poke around under the hood, or you can have it cleaned at just about any auto service shop.

Of course, there could be a hundred or more other possible causes, but this is the most common - and probably the easiest/cheapest to fix.

    I would also check the idle air control valve, these have a bad habit of plugging up.

Sometimes my 1997 Ford explorer will start and other times it does not. What could be the problem. The battery is fine and I recently had the battery cables replaced.

Could be as simple as the neutral switch out of position if it sometimes won't crank over. Turn the switch on, depress the brake, and pull it to neutral position to see if will crank. If it will, readjust the neutral switch while in park position.

My 1998 Ford Explorer runs rough under hard acceleration

New plugs and wires?

Double check to make sure that you've got the routing and firing order right... if you have 2 switched, the car may still idle well but then pop and sputter on harder acceleration.

The next step would be to run some "Complete Fuel System Cleaner"... If that's the problem, you should see results within 20 miles or so.
