Figured I'd get more opinions.
It's a 97 gt40p explorer engine into my 86 gt vert.
It's SPEED DENSITY, not mass air.
I'm running the explorer 19 pound injectors, explorer efi intake, 1.7 roller rockers (double and triple checked the adjustment, I'm good here and positive of that) with tfs valve springs.
It's got a stock mustang ho roller cam in it, and timing set to 12 degrees.
Problem is, it runs like complete ass. it idles like it's got a wicked cam in it (bad bad miss) then I rev it up, and it misses like hell.
Dist plugged in right, firing order got right. Plugs are new (got the right ones, the autolite 746 was it, whatever is oem for an explorer) wires are good.
It runs RICH RICH RICH RICH RICH. fouls every plug I put in there black as hell in minutes. Smoke coming out the exhaust is so damn rich it burns your eyes.
stock mustang fuel rail, non adjustable fuel pressure.
Here is the kicker, before dismantling everything, the old engine ran like a top and jUST passed cali smog, so that's why I don't suspect bad parts.
Here is what has been done:
Fuel pressure:
16/17 with motor off
33/34 running
computer codes: koeo : 81
Koer: 4,12,21,22,16,13
vacuum: 12 to 13, slight wavering. This could be due to the engine idling and loping like crap too. (stock ho roller cam)
I swapped out the ect, and it did nothing. I have not swapped out the map yet, but I personally don't think that's the problem, it was just working on my old engine.
I've double checked vacuum, and have no leaks.
Also, i'm bypassing my tad and tab solonoids, and currently don't have the smog tube or bypass stuff hooked up. I'll be running the smog tube, but didn't plan on running the bypass stuff.
any suggestions here? i'm going insane.
