s4 idle smooth, with no power
i have a s4 n/a, stock everything except header/exhaust.
it will start (every time), idle smoothly. when in load, no power to be found. no load it sound like a two-step is coming on immediatly. in load, trying to drive it will go, slowly and try to step on the gas it falls on its face badly, almost dies(i think it would die if not rolling already). checked timing, no vac leaks, fuel pump works(key switch wired). when pulled the plugs they were very black from the rich fuel
the only thing i have not checked was comprssion.
all of this started after a bad main relay. when it went out my tach was jumping from 500 to 1.5k+ and poping and backfiring badly
just needing some help! thanks

connected a good/working one and when i turned the key the tach flickered and it started.
i could never get power coming out of the relay, only going into the relay
what else to look for? engine ran fine/good untill then(when relay went bad)

main relay still working good. still have rich issues. swaped out AFM, main coil, plugs...
swapped fuel pump and it ran great once, spun in 1st, still going in sec, after that pull it started acting up again. one time when i was checking timing i left the jumper wire in and it ran better than after i pulled it out? any sugestion?

Check your plug wires
I know it sounds stupid but make sure you have L1/T1 going to the plugs on the front of the motor and L2/T2 going to the plugs on the back of the motor. I had the same symptoms and that is what it turned out to be.
