k heres my problem.. as most of u no i put a b18a1 in my 90 ef... i did the dpfi to mpfi swap as well.. my problem is.. i have no power ( i mean not as much as it should .. the car is pretty slow.. im throwing no codes.. wiring is done right ( checked it many many times)... i havent done a compression test.. but the motor looks like it was taken care of.. i was getting code 4 for a while but that went away after i rewired it... oh ya the timing belt looks a little loose but doesnt look like a jumped a tooth..( i think an ways) any suggestions on what it could be..

 

how's the timing at the distributor?

 

the timing on the dizzy is fully advanced

 

have you tried a new distributor or ecu or... oops... maybe its because it is a 4-door and its heavy mr. Bill mexican.

 

na thats not it.... i pretty sure theres not that big of a difrents in weight ... i mean a stock da pulls harder then this does... and yes ive tryed a new dizzy and a new ecu.. that i jacked from this white kid :P

 

Eh vato, Now I'm gonna beat y0 ***!

 

^^^^lol

 

i would check cam/tdc timing.

 

ya i was thinking that ill be looking into that today

 

sounds like your timing might be off...my car had the same problem a while back. Does it waste more gas then it should?

check your timing !!!
