I have a 91 5.0. Not too many mods mainly bolt on stuff. I have a BBK SSI Intake w70mm Throttle Body and 76 MM MAF, MAC Full legnth head, MAC PRO Chamber, MAC Dumps,24lb injectors, 155 fuel bump, underdrive pulleys, a/c dead pulley and MSD Blaster Coil. I just started the car last night and set the timing to 14 degrees. I took the car around the block and noticed that one I can't get full throttle and two when my tranny shift into 2nd gear the car starts to shake really bad. It also sound like I have multiple detonations. I am stumped almost to the point of taking it in. Any suggestions?

Have you replaced anything or done any major repairs recently?

Dump the codes and see what the computer says is wrong…Codes may be present in the computer even if the Check Engine light isn’t on.

Here's the link to dump the computer codes with only a jumper wire or paper clip and the check engine light, or test light or voltmeter. I’ve used it for years, and it works great. You watch the flashing test lamp or Check Engine Light and count the flashes.

See http://www.troublecodes.net/Ford/





If your car is an 86-88 stang, you'll have to use the test lamp or voltmeter method. There is no functional check engine light on the 86-88's except possibly the Cali Mass Air cars.



89 through 95 cars have a working Check Engine light. Watch it instead of using a test lamp.



Codes have different answers if the engine is running from the answers that it has when the engine isn't running. It helps a lot to know if you had the engine running when you ran the test.

Trouble codes are either 2 digit or 3 digit, there are no cars that use both 2 digit codes and 3 digit codes.

For those who are intimidated by all the wires & connections, see http://www.actron.com/product_detail.php?pid=16153 for what a typical hand scanner looks like. Normal retail price is about $30 or so at AutoZone or Wal-Mart.

Or for a nicer scanner see http://www.midwayautosupply.com/pc-7208-90-equus-digital-ford-code-reader-3145.aspx – It has a 3 digit LCD display so that you don’t have to count flashes or beeps.. Cost is $30.
