YOUTUBE VIDEO I POSTED EXPLAINS EVERYTHING AND SHOWCASES ISSUES. THANKS.
Hey guys I'm having problem with my 1994 v6. I'll start with turning it on. When cranking, it usually takes quite a while, and takes less time each time if it has recently been started. The check engine light was not on but now is. The MAIN ISSUE is that after a while the "red line" persay drops. It starts at actual redline, then progressively gets lower. It backfires and bogs off of 4500 rpm, then 3500, then 3000. Sometimes 2500 if you're hard enough on the throttle, or if you've been driving a while. I just changed the fuel pump, cleaned the throttle body, and changed the oil. There is a pretty bad antifreeze leak, from both hoses, but I'm fixing that in a few days. After a while it won't start without trying several times and/or giving it some gas to keep it up. I had a top of the head diagnostic that it is the fuel pump, but you can clearly hear it work and/or turn on when you crank the key to accessory. It has a brand new battery. If you have any expertise or knowledge, it is much welcomed. Thanks again. And this is my daily so this is very severe for me.

Spark plugs, fuel filter, plug wires, coil pack. I'd go in that order, that's based on likelyhood as well as cost. Also head to advance or autozone or what ever and have them do a free code scan and tell us what codes you getting from that check engine light.

Hey I've done all that, except for the cool pack. Neither of them read OBDI for free. Thanks for the reply.

94 mustangs I thought were obd 2. Swap a new coil pack in. If that has no effect clean it up good and get your money back.

From things I've read obd2 became standard in 1996.

Standard in the car world maybe, but an obd2 plug tuner can tune a 94 and up v6.
