i just did the mpfi swap on my 89 crx dx. i had a problem at first with the injector o-rings, but replaced those with oem one's and that solved it. the problem is now it will start and idle fine, but as soon as you give it some gas, and let off, it will sputter and die.....help!

 

bump for some info.....

 

check the following....

fuel filter......
throttle position sensor .....
bad gas......
plugs.........

 

is your check engine light throwing any codes...?

 

ok i checked for codes and i'm getting a IAT sensor code. i'm pretty sure when i did the swap, i mixed up the IAT and EACV sensors so i think thats the problem. i'm also getting a Crank angle sensor code, but i think that is because when i wired the si dizzy plug to the dx harness, there were two solid white wires that i prolly got mixed up....i will keep you posted, thanks for the help...
