Re: 1990 Mark VII Engine Surge
I'd suggest pulling the computer codes and having a poke around the Mustang forums as the engine is pretty much the same. It could be any number of things such as the MAF sensor is dirty. Having the codes should help you locate (or better understand) where the problem is. A sensor of some sort no doubt.
I have two 1988 Mark VIIs, so if you need me to confirm something I can take a peek at one of mine and get back to you.
All kinds of good info can be found by Googling 'Ford Fuel Injection'. The web site was especially helpful for me as it showed me how to read the computer codes and what all the sensors and actuators do.
A little knowledge is a dangerous thing!
