Ok so I have a 92 5.0 h.o. in a 91 lx coupled with a painless harness, I got it running, would start quick every time and I could use the full throttle range, but didnt run the best so I checked timing with spout disconnected and base timing was at between 20° and 22°!!! So I retarded the timing to about 13° and idles and drives beautiful........but now it takes a good 4 or 5 revolutions to fire off and start also I can give a slow to moderate acceleration but if I get into the throttle heavy it bogs bad and falls on its face, I tripled check base timing and 13° and with spout in around 23°, fuel pressure is normal. Tps is adjusted to .98 but not verified if it's bad at wot, plugs are motor craft platinums basically new but may be fouled, was told to try auto light 25s? But either way I fix timing and now hard starts and bogs at heavyish throttle but before at way higher base timing it would start fine and accelerate at any throttle but run like poo..........wth any help????

- check to see if your balancer has slipped - I highly doubt you had 20 degress of base timing.
- put copper motofcraft 3925 plugs in. Platinum plugs are not what is called for
