Integra bog issue.
Ive had my 92 Integra GS-R here for a few months, and I have a gremlin I have been slowly chasing. Its like, all of the sudden, it will hit a wall when driving, like sucking through a straw, you can feel when it starts when you are on the throttle and it kinda stops the car from accelerating. It will do this until around 5kish and then open up like its supposed to. Sonetimes it runs great. So far, I have done whole dizzy,Plugs, wires, cap, rotor, fuel filter, air filter, and cleaned the intake mani with carb cleaner. Its slowly getting worse, and Im kind of getting worried it could be something big. At this point in time, and my next thing im doing, is taking off the Catalytic converter and knocking all the stuff out of the inside of it. The current cat is the stock one, and the body has 250k~ miles. Any other suggestions are awesome! Thanks guys! It has the stock B17. It runs fine cold, starts acting up when warm. New dizzy, plugs, wires, fuel filter, main relay, new battery terminals. Unplugging tps, map, or o2 doesn't change much. I can barely start on a hill without riding the clutch.
I have a fuel pump, pressure regulator, injectors, map sensor and a compression tester on the way, I am not excited about the fuel pump but I'm running out of stuff to replace. Side note, I have the timing fully advanced because it runs alot better than with it anywhere else. I checked the timing belt and it looks fine and tight. NO CEL.
Any help appreciated, sorry about being so lengthy just want it fixed

Re: Integra bog issue.
I have a 94 GSR with the exact same problem, it also has got worse the more new parts I put on. I have new water pump and timing belt, distributor, every sensor other than evap and tps.... seriously people we need help before this becomes an epidemic among tegis...like herpes.... please for the love of Honda, HELP!!!
now half my fuse box is out....all interior lights and bells if keys are left in ignition and all power winder controls are not working... this happened after I change idle control module on the back of intake manifold

Re: Integra bog issue.
I swapped a '98 GSR engine into my LS Integra and sometimes I feel the car do the same thing in mid-range revs. It'll spit and sputter like it's not getting gas or something. And then after I've come to a complete stop, and try to accelerate again, it feels like the car wants to fall on its face. Like there's no resistance behind the pedal, and it doesn't accelerate any faster for the split second it takes to start pushing down on the gas pedal.
I've noticed that I have an intermediate CEL for "TPS low voltage", it comes and goes but I believe this is related to my EVAP wiring issue, because it shares a ground wire with the TPS sensor.
I'd be interested to see if anybody has some insight on this issue.

Guys check your ignition timing! set the timing with a timing gun to spec!
Double check your spark plug and the spark plug gap!
Test the ECT sensor! sounds like the ECT sensor is not working correct telling the ECU the engine is not warm when the engine reaches OP temp. When the engine is cold the ECU has cold start compensation and as it warms up the ECT tells the ecu what the temp is and it adjusts the fuel trim.

Re: Integra bog issue.
Clean the thermostat ground first! make sure its nice and clean as well as the other grounds.

Check for any cuts in the wiring on the IAC harness, inspect the plugs themselves as well for any wires worn or being pulled out the plastic plug.
Clean your thermostat ground and check the TPS for any cuts or damaged wires coming out the plug. Make sure your using a GSR ecu and that the Vtec solenoid is connected to the ECU to properly engage vtec or else the engine will run like **** and have no top end power or VTEC. Also make sure ignition timing is on point! use the gun.
There's one on the Thermostat one on the valve cover, one near the back of the intake manifold near the brake booster and shock tower location. and one is connected from the chassis to the trans.

I have brand new all of those parts on... even had timing belt and water pump replaced beforehand

Re: Integra bog issue.
Did you calibrate the TPS with volt meter when you replaced it!
