loss of power

i think the first place you should start is by pulling codes. See what the computer thinks of the situation. Check Jrichkers site for code information or just search this forum. Next i would change out that fuel filter...its a cheap part and should be done every couple years anyways. Maybe run some fuel system cleaner through there after that.

I would also check/clean the O2's to see if they are dirty. Then check the ECT sensor for proper resistance according to jrichkers information. Clean the MAF element, EGR valve pintle/seat, and the ISC valve while you are at it.

That should be a good start...and if it doesnt fix it...then you just did all the right preventative maintenance and you know it will be in tip top shape after you get this problem solved. Good luck

Did you find jrichkers info? If you do a search in here for codes you will find it for sure! Gotta start with the codes!

EDIT- I found the website for dumping the codes and there meanings

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 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.
