My 97 has been stumbling and hesitating for a couple weeks now. The check engine light comes on and I pull the codes and I get the same 3-4 each time then erase them and keep going as I havent had time to tend to the problem until now. The codes i got were cylinder 8 misfire, some sort of...

Driving down the highway and my interior lights started to dim, then eventually shut off completely. Before dying the system check display read "check charging system." When reached my destination and turned the car off, I couldnt restart it. The next morning I used a multimeter to check the...

Has anyone used a MAF sensor cleaner, particularly the one made by CRC? Says if sensor is dirty, this stuff will add 4-10 HP to the wheels. Its like $7 for than Id ever need so it sounds like it might be worth a shot.

Ive narrowed my hesitation problem down to fuel filter or possibly clogged injector. Im going to replace the fuel filter first since theyre so cheap. Will i need a fuel line disconnect tool to get it off and do i need to trip the fuel inertia switch prior to removal? Anything else I should...

Im currently changing out the spark plugs on my 97 and Im very unfamiliar with the new coil-overs. Obviously, I cant use cobra wires on this car but Id like to get performance wires, maybe MSD. Do they sell coil-overs for this car? Do the coil-overs come with boot and coil together or are they...

Bought a 97 mark viii a couple weeks ago and been driving it daily with no problems. Today on my way home from work I stopped to get gas as I was running below E with less than a gallon of gas in the tank. I put $20 in the tank and pulled off. All of a sudden, my car is seriously stuttering when...

Im think of ordering a few things from rock auto. Does anyone know about the airtex or trutech brands that they sell? These two brands seem to be excessively cheaper across the board causing me to wonder about their quality. The trutech fuel pressure regulator is especially cheap at $17.21 with...

Can I check/set the timing using a timing light on my 93 or do I have to tap into the computer?

Had my car (93 Mark VIII, 170K miles) smog checked today and the technician used the words "killing machine" to describe the vehicle emissions condition. In the hydrocarbon test, my car emitted 341 PPM. Max is 81 and anything over 266 is considered a gross polluter. In the CO test, my car...

Putting a set of cobra wires on my car but can seem to figure where each wire is supposed to plug into the coil pack. On the engine block side its obviously 1-4 and 5-8 front to back on eacj side but i cant make sense of the coil side of the wires. Any help?

My 93 Mark VIII is bone stock and strong at the factory 280hp. Looking to add 20 or so HP without spending too much money. Ive heard about the intake mods and not looking to use NOS. What else can i do?

The plug wires on my 93 look to be the original wires and at 170K miles id think they surely need replacing. Called the ford dealer and they want $225 for new wires so I figured Id scour the junkyard for a better set. I pulled matching 8mm motorcraft wires from a 97 Continental for $8 and id...
