I have an 87 GT with 160,000. miles on the original motor no smoke no loss of water.I'm having a problem with it when it first cranks for the day. Everyday it's the samething the car starts good and idles good. But when i decide to drive away it cuts off. If I press easy on the pedale I can leav. Before I'm a mile down the road I'll stop at a store or someplace just to see how it's going to do. The car will run great then no problems and it's the same everyday. What could this be (fuel pressure loss, a vacume come loos,blow-by,) or a number of other problems?

 

can you hear the fuel pump prime when you first start it?

whens the last time you did a complete tune up?

 

start checking **** liek EGR, your tube could be clogged, start checking plugs, cap/rotor and etc

 

yeh I can hear the fuel pump prime before I crank it. The fuel pump is 1 year old and its a 190lhr fuel pump.

 

I suppose it could be the fact that it don't get many tuneups. I have three mustangs and keeping up with the upkeep and mods are mindcrushing. Well I guess I'll start trouble shooting parts.
