Big Help in a hurry!!!!

check all spark plug wires, maybe change them and the spark plugs... Its possible the maf has gone bad... No engine light on? i think the way it sounds its somewhere with plugs

i would get the codes pulled, it may narrow down ur search

yeah, pull codes asap. but it sounds kinda like a TFI modual gone bad.

you can buy a code scanner at any autoparts store or wal mart or you can do it with just a test light. jricher has a whole write up about it. This is one of the sites that he lists. http://www.troublecodes.net/Ford/

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.

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.

sounds like a MAF problem.. had a issue with a 89 that was maddd crazzy when its MAF was screwing.. my 2 cents
