I have a 1985 Mustang with central fuel injection. Under load or wot it seems as if it putts and shoots a mist of fuel into the throttlebody.

I was thinking it was the timing or a mix up with some wires. Previously i had a fuel injector leak but it seems i have that under control now after i replaced the seals. The guy i got the car off said he had changed the wires and did the timing but it was set wrong. ( car would die after putting it into gear ) I adjusted the timing without a gun in hopes to make it run a little better. It goes into gear but when i rev it, it putts and shoots a mist of fuel into the tb.. I need to find a way to get this car driveable asap! My apartment wants to tow it because i havent been driving it, ive been trying to get everything straight first.

Any opinions i thank you in advance!
 
I picked up a timing light. I changed the plug wires around to a firing order i saw online. Car ran a lot smoother. However it was the wrong firing order. Is it possible the distributor at tdc isnt on the number 1 cylinder?
 
Putting the distributor back in is fairly simple. Pull #1 sparkplug, put your finger in the sparkplug hole,
crank the engine until you feel compression. Then line up the TDC mark on the balancer with the pointer
on the engine block.

The distributor starts out with the #1 plug wire lined up at about 12:00 with you facing it. Align the rotor
to about 11:00, since it will turn clockwise as it slides into place.

Align the distributor rotor up with the #1 position marked on the cap, slide the distributor down into the block, (you may have to wiggle the rotor slightly to get the gear to engage) and then note where the rotor is pointing. If it still lines up with #1 position on the cap, install the clamp and bolt. If not, pull it out and turn 1 tooth forwards or backwards and try again. Put the #1 spark plug back in and tighten it down, put the clamp on the distributor, but don't tighten it too much, as you will have to move the distributor to set the timing. Note that if it doesn't align perfectly with #1 position, you can turn the distributor until it does. The only problem is that if you are too far one way or the other, you can't turn the distributor enough to get the 10-14 degree optimum timing range.

10 degrees BTC is towards the drivers side marks.

Simplified diagram of what it looks like. Not all the marks are shown for ease of viewing.

ATC ' ' ' ' ' ' ' ' ' '!' ' ' ' ' ' ' ' ' ' BTC

The ' is 2 degrees.
The ! is TDC
The ' is 10 degrees BTC
Set the timing 5 marks BTC. Or if you prefer, 5 marks towards the driver's side.

At this point hook up all the wires, get out the timing light and start the engine. Set the timing where your car runs best. Don't forget to disconnect the SPOUT jumper connector when you set the timing, and plug it back in when you finish.

The HO firing order is 1-3-7-2-6-5-4-8.
Non HO firing order is 1-5-4-2-6-3-7-8
