1999 4runner 4wd v6 surge and die with cold engine

hello all,
at 101,000 miles it had the check engine light on. i undid the battery and put some water in it and cleaned it.
changed spark plugs with bosch supers and medium quality wires(which i know better now then to use those),oil + filter,transmission + filter,air filter,and pcv valve. i did not change the fuel filter.
ran fine before, it then sputtered and stalled. re-checked wire order 3x. no luck. went to auto store, chilton manual had exactly what i had for wire order, the guy pulled up different wire order on computer. so i tried his wire order, no luck. then i just switched them all over the place.
then i put old plugs(denso) and wires back on. the plugs i pulled out were blackened fouled. now it is surging when i start it, up to about 1100rpm down to 300rpm or so then surges back up, does that a few times and then stalls.
i would like to know what plug wire is where on the engine if anyone can help me with that.
can i still get a code since i have had it started (and surging)if i undid the battery and pulled the efi fuse to reset the computer? does anyone have a list of codes and their meaning(im pretty poor)?
i would also like to know what i might be missing maybe with this surge and die. tps,egr,choke,coil,maf,etc ???
please help im exhausted with this thing. :confused: :confused:
thank you,thank you, thank you in advance,

Good day,
I had piss poor luck with anything BUT the OEM Toyota wires really nothing to be gained that warrants the cost of HP secondary ignition components on this motor. Same for the plugs except for longer life on some of the plats.

You say it "worked before you fixed it"? :confused: So take a good hard look at every thing you did and verify it's correct. I beat my head against the wall with those new aftermarket wires, then broke down and bought the factory wires and the rough running both at idle and on the road went away. :banghead:


Double check the gap on those plugs, BTW blackened plug electrodes can be OK unless the build up is significant.

Check the rotor and cap. However there can still be cross arcing inside a "normal" looking clean cap, especially if it has "wiped" clean this can leave or "smear" a conductive path. For the price a new cap and rotor is worth it.

There is a sticky post at the top of this forum that has some of the 1993 FSM pages in PDF here is the firing order and other goodies.
