i put a 94 accord ex motor in my 91 accord. i swaped the intire wiring harness from the 94 accord into my 91. the problem i am having is that the car will idel but as soon as i touch the gas the car dies. Any little bit of extra air in and the car dies. A little about the car.... It has special vtec rockers from web cams that lock the car in vtec all the time.. reground cam from webcams... Webcams racing springs and over sized vavles. The head has been shaved .035 have forged rods and 13.1 compresion pistons. Light weight flywheel. I have not upgraded my fuel injectors yet, planed on having engine managment tuned and them installed all at one time. I jsut wanted to give a little insight about the motor so i could get some help. Now if i ground out the fuel injection system and leave the injectors open all the time i can rev it up but it eventually floods out at idel. anyways thats what i know any help would be greatly aprciated

 

you might be looking too deep. all your your intake components properly secured? sometimes if you leave something off, like a sensor or leave out an air filter, itll create a situation just like you described. if thats not it, sorry and gl!

oh and btw, please try to be a little more specific in the title of your post, thanks!

 

thanks alot man.. I figured out the problem i had hooked up a pressure hose to the MAP sensor instead of a vacume hose lol it didnt like that. Runs like a champ now

 

lmao, good catch

 

same swap except I used the original harness. between 1-2k rpm the engine revs. I swapped the a6-a11 pins and it didnt help (read in thread would help)
