Backfiring and no power 1996 fd
Hey guys. I just recently got a 96 fd. Ran fine while driving it home.
Then randomly it felt like the engine ignition cut if I gave it any throttle under load. Just backfired like all hell.
Also struggled to get past 3k rpm.
I can get it to drive around as long as I don't give it more then 10% throttle.
Car idles around 800rpm but does backfire ever so slightly.
Any help would be greatly appreciated!

to my non-FD-experienced ear, it sounds like limp mode to me. start by checking your MOP function.
if the MOP checks out fine. my next suspicion would be a dead/clogged cat. however, i would be remiss if i didn't tell you to check the obvious as well ... the ignition system (coils, crank sensors, etc.)

My vote is limp mode. If anything BUT vacuum is sensed in intake, fuel is cut and timing won't advance. It will rev normally as long as you do it slow enough to keep vacuum, but there will be no power.
I think there is a way to check for CELs on a RHD, but I don't recall how off-hand. You could search elsewhere on the board. diabolical is right, one of three CEL codes associated with the OMP/MOP on our LHD models is a common cause of this...but there are others.

Accidentally cleared all codes while swapping out my stereo. Problem seems to have gone away.
I've ordered new intercooler piping, spark plugs and wires, oil filter, fuel filter and grounding points. Hopefully things will clear up even more once I get those in.

Where would I check that?? I'm not 100 percent certain where the OMP is.
On another note I've ordered a rotary aviation OMP adapter. So hopefully that will clear things up maybe?

^Not if it really is the OMP and you're on the stock ECU.
Get a copy of the Factory Service Manual, preferably one for RHD, but the LHD for North American models is available in the 3rd Gen. stickys.
And it's probably better if you don't buy things, especially aftermarket parts, when you don't know where they go or what they do.
This is how you pull codes on a FD meant to be in North America http://www.fd3s.net/engine_codes.html
I'm not sure how to pull the codes on a car with the silly left-hand shifter.
