This is driving me insaine,

I parked the car last winter, it ran mint. Not a single problem. I Took it out for the first time last week and it runs like crap.

Is what the problem is, is that at first it was backfireing throught the intake. I pulled codes and it said that the EGR was sticking. Well I Blocked off the EGR and for the switch if I held it in there was know check engine code, thinking the computer thought it was close. I beleve this is the same thing the EGR block off kit does but they use a diode. Well I thought it ran better. I replaced the fuel filter, wires checked and rechecked timing 16, New intake gaskets. I have 2 vacume hoses, one for the brake booster and one for the heater controls. No vacume leaks.

Well now when I start it up and drive it ( even if its still hot or just turned it off) I first 30 seconds or so of driving it ,its boggy, sounds as if its sputtering, missing thean its gone and runs fine!??? When I give her the beans sometimes it bogs down for a few seconds too, but if I let of the gas a hit it againe it fine.

Please help, this one has got me!!!

Dump the codes and see what the computer says is wrong…

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.

See http://www.troublecodes.net/Ford/
OR
See http://www.dalidesign.com/hbook/eectest.html for more descriptive help

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.

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 Walmart.

Or for a nicer scanner see http://www.midwayautosupply.com/detailedproductdescription.asp?3829 – It has a 3 digit LCD display so that you don’t have to count flashes or beeps.. Cost is $33.
