Hi all I have a 1966 mustang gt mostly original as my first car I've been driving it a lot recently and just yesterday while driving at any constant speed it misfires. But when I accelerate it's fine I have just put on new cap, rotor, wires and coil. It ran great with the new parts but now it...

Hello all. I have a mostly stock 88 gt (except for 2.5 inch pipes, cold air intake, maf conversion), and I'm have missfire problems. The car has ALL new engine control sensors that I've steadily replaced during the 2 years I've owned it. There is a vacuum leak in the throttle body body where the...

Hi, I currently own a 1993 hatch 2.3 lx (first car). I've put about 25000 km on it since I bought it at the end of August. Recently it has been giving me problems and I can't seem to find what it is. The car seems to intermittently run on 3 cylinders. It has progressively gotten worse over the...

I blew a head gasket in my 98 GT with 4.6 and replaced it with a 4.6 from a Mercury Grand Marquis same 4.6 but from a 95. It seems to run great and getting around 21 mpg but between 60-80 mph it has a miss to the engine. If I unhook the vac line to the EGR valve and plug the line, it runs great...

Hi everyone, I recently bought my first Mustang for a Chevy dealer (ironic, I know). It had some issues but I got a good deal, 2002 Mustang w/ 59000 - $6600. On my way home it started to miss extremely bad, the air conditioning quit and the service engine soon light came on. I changed the spark...
