car bogging when i hit the gas???
I have a 90 crx with a turbo'd LS. The car starts and idles fine...but when i hit the gas it bogs for a second then the revs go up. I believe that its a vac problem because while its idling i have 20 vac but when i hit the gas it goes straight to 0. I thought that it was becase i had 4 lines off of 1 source...so i t'd the gauge and the fmu to the fpr and the bov and wastegate to the map sensor. The only thing im worried about is the evap purge...i didnt know where to put that so i put it on the throttle body. What the hell is my problem? Thanks

It should go to zero when you hit the gas if you are flooring it.

Re: car bogging when i hit the gas??? (shermanyang)
that could be...b/c sometimes it doesnt want to start and i get a code 16 and 41 ir something. The 16 is injectors and the 41 is primary 02 sensor heater. Ill try hooking up my friends and see if that helps. Any other ideas?

Re: car bogging when i hit the gas??? (sCeRaXn)
so you are running an FMU with an inline pump...you have any way to monitor your fuel pressure?
i learned this weekend two things that it could be...
#1, with the FMU and the inline pump, there could be way to much pressure causing your injectors to flood your engine with gas...causing the bog
#2, when there is too much pressure to the injectors, they can lock right up...too much pressure keeps them closed although everything else thinks they are opening and closing when they are not. im not sure if that would cause a bog but im sure it might throw an injector code after a couple of cycles

Well as i said before...it did this before installed the inline pump. And i dont think that the fmu would cause it to to flood. Ive never heard the thing about the injectors sticking but that does sorta make sense. Has anyone else ever heard of this? Any other opinions on what could fix it? Thanks

Have you tried any small changes your self? Trouble shooting it yourself is half the fun in this game.
Good luck, hope you get it running
