eg33 swap wont rev

[cruisen_15]

ok so did the 33 swap on my 92 legacy, well ive got it to idle and it kind of has a smooth idle. idles around 1000rpm and drops to 750 or so and climes back to 1000. so right when i give it any gas at all it misfires,bucks and dies....

only codes i can pull are code 12 (abnormal signal at ignition switch) with the green T connecter connected

and i do get a code 34 (egr valve innop.) i deleted this part so i epxpected this. this comes on with my black connecters connected

any ideas? i keep goin through every damn sensor but im stuck at the moment

also using a green jecs maf, are obd2 mafs different than obd1's? didnt think they were

If you have another MAF id try swapping it out first just to eliminate it.... Idling ok then stalling under any throttle is a symptom of a MAF problem, among other things. So you have the EGR vacuum ports on top plugged right?

[cruisen_15]

hey thanks for a reply, well i put the maf on my 98 gt and it worked fine... i had a code for the maf but fixed it by fixing its power wire coming from the ecu. now i get no code for it... is there any documents here for testing the maf wiring

as for egr yes it is now a vacuum/boost port but is closed for now

at idle im getting 20 on vacuum so i doubt a leak anywhere

hmmm, i know when i had the code for the maf i just took it off and it still acted same way as if i had a maf connected. seriously these wiring diagrams have many errors...

[cruisen_15]

what i dont have wired in:
all egr setup
iris
auxillary air control (sensor that has hoses on it undermanifold)
nothing for a/t (not an svx wiring harness and i did a 5sp swap)
speed sensor 2
all a/c swtichs
power steering switch
trq control
fuel pump discharge control
atmospheric pressure sensor(a/t)
recirc gas temp sensor
49 state id

02 sensors not currently hooked up

[cruisen_15]

holy crap. found more errors with these wiring diagrams, i based my wiring off this info well it turns out they have number 1 and 4 signals to the ignition mod. swapped.....

so tomorrow ill swap the two and hopefully it works, missing on 2 cylinders would probly give me the symptoms ive been having right now

Wow man are you using an FSM or just some print outs?

Hopefully hes not using the wiring diagrams from the online SM exclusively. I should have an asterisk by my signature link

[httrdd]

I mean color to wire print outs not scans. I wish I knew that you had the FSM in your sig for my swap!

I meant.... the one in my sig may have a few correctness-challenged entries, although is very useful otherwise.

[cruisen_15]

yes i have printouts of the diagrams in your sig aswell as printouts of ecu pins and what they go to, so far your sig diagram of the crank2 and cam sensor pins are swapped for (+) signal. went back over more diagrams and still find my 1 and 4 are connected wrong.

I'm pretty sure you have to wire in your O2 sensors if you want yo get your engine running correctly. Don't see the point in trying to trouble shoot until you have all the required pieces in play.

[cruisen_15]

yes but even without 02s plugged in it should still run and be drive-able, where as my car is not able to do at the moment

How confident are you with the timing? it could be that you are running on only 3 cylinders maybe? Wish I could be of more help...

[cruisen_15]

im dead on with timing for sure, thats one thing that always got me when workin on subie motors, so when i put the motor together i made SURE it was right on

Is all your intake plumbing installed correctly? Do you have any cracks or leaks?
