just swaped the map sensor, same problem

more suggestions please

 

Hook up a fuel pressure gauge to the top of the fuel filter and measure the fuel pressure actually getting to the fuel rail. I know the pump, injectors and everything are new, but that might be a problem. I had a friend with a B18C1 swap in a '92 Si and it would just fall on it's face above 4000 rpm. They tried everything they could think of and finally hooked up a fuel pressure guage and found that the line that goes from the filter to the fuel rail was causing some obstruction and no actual pressure was getting to the rail (enough to run, not enough to sustain WOT). Replaced that line and the motor ran great. Did you try a compression test yet?

 

TPS had a bad connection inside it. I ground off the pop-rivit lookin things & installed a new one just as an off the wall thing to do coz i've changed everything else. Turns out that it was just a bad connection in it coz it was working intermitantly & just failed but the wire test was working when i tested it that way. very strange but i'm glad that i've finally figured it out. Thanks for all the help guys, even through my frustrated comments!

:yay: you found the problem...good to hear....now get that bish to the track

 

awesome man, glad to here it, when you gonna turn up the boost on that whip

 

when he figures out his uberdata and gets rid of that retarded vortech riser h:

 

:ghey:

Glad you got it figured out. Did it have a dead spot on it?

I just got my both of my buckets running right again this weekend. Not that anyone probably cares, but my civic needed a new distributor cap at 20k miles. Now it runs great.

 

thanks for the help guys.. & for those who were wondering.. it's stayin at 4lbs till i get my injectors & my uberdata setup.

It's not bothering me at all yet tho, i shut up most of the shit talkers at just 4lbs.. i love there reactions! I'll probly stay at 4lbs for another month or so, until i have the cash for the injectors & what not.

 

why is that :ghey: :thinking:

 

'cause I'm quoting you... with the right answer... that you posted on post #4... and it took 33 posts and probably a lot of parts he didn't need to fix it.

You nailed it man. I'm being ghey for quoting it.
