b16a . 1991 integra ..swapped manifolds to a aebs typhoon and started it ran good then it was on e ran out of gas then ran like crap ,i changed fuel pump fuel filter ran cleaner through it hasnt done anything i press the gas it falls on it's face has no power cant rev past 3,000 and 4,000 and it is very lean when about 15% throttle it will rev higher but when full throttle it bogs and pops out the intake i have messed with the tps censor put other manifold back on still havnt figured out whats wrong it runs lean now

 

anybody have an idea? posting for a buddy of mine

 

I had the same exact problem with my JDM B20 Vtec swap, since i had to cut the wire harness on the distributor because the plug didn't wanna come out of the JDM cut portion of the harness so I then use butt conectors, that didn't make a positive connection, I soldered it then and just used shrink tubing, car ran like a champ. Bottom LINE it is most likely your distributor not getting the timing adj. to your ecu so your cam timing is retarded too much. Try that out and see if that works.

 

thanks ill try it
