So I have a 97 Acura integra, b18b1, boosted. The problem is, she keeps stalling out, but it's more like a surge. The tac keeps bouncing around even though there's no rev increase, she shimmers while backfiring occasionally. Won't go over 25-30 mph. She's stalling. I've changed the spark plugs and wires, distributor (twice), fuel filter, all the usual suspects, but nothing. Still doing the same thing. I have a obd1 with a chip, not quite sure if it would be a ecu problem. Completely stuck, please help!!

 

So does the engine die and shut off? or does it surge?

When the tach jumps around its usually the ICM inside the distributor going bad but you said that was replaced twice.
Unplug the ECU or the battery for a few mins to re set the ecu in case there is a code causing the engine to go into limp mode.
What kind of "Chip" do you have or what EMS program? can you connect a laptop and check the EMS for any codes?
I would recommend to get a real EMS program not just any online chip, they don't run right and they glitch. Invest in a quality EMS like Hondata S300.

 

Well when I replaced the distributor, immediately after we drove up the Rhode twice, ran fine, as soon as I got into boost, that's when she started acting up, (both times). We just found a wire that was for an engine ground, that was broken off from the cylinder head, could that possibly short out the ignition coil? It's a throwback build, but it was legitimately tuned at innovation autoworks, but it was like 8-10 years ago. I actually like the way it's set up though, I get hondata is a great option, but I like it the way it is, or was!

 

The grounding wire is most likely not your problem, but its worth fixing to see if something is getting too much power
