Car loses power
First a little info, I have a 1987 lx 5.0 that has been converted to mass air off an 89. This problem has only occurred twice but in first gear at about 4500 rpm the car just completely falls on it's face. But right after that happened I got on it again and it pulled harder than it ever has. Any ideas, thanks.

Welcome to the forum.
I'd start by pulling codes, see if any are there that may point you in the right direction.
Then start looking at your fuel system, plugged filter, regulator, pump, lines, etc.
And just to clarify, this only happens in 1st gear ?

OK, don't just start throwing money at this without verifying. If this only happens in 1st gear, I'd rule out the pump. The filter is cheap and easy, and probably needs the be changed anyway.
And definitely pull codes before anything, it's free and easy, and could save you alot of headaches.

I tried to pull the codes last night, but either there wasn't any or I wasn't doing it right. Do you know what color the self test input wire is, because there are two wires that look like it. One comes off the same harness and the other one comes off a harness right next to it. Maybe I wasn't using the right one. Or my check engine light might not be working.
