No Low end power
Well If anyone has seen the last few threads of mine...i finally got all my jspec intake and such all hooked up. Car started right up no problem. And my idle problem seems to be fixed too now so thats always a plus. She idles around 900...no movement at all.
Anyways...i ran into another problem. This is a 87 TII btw. I basicly have 0 lowend power. It is tough to even get the car moving. But once she starts moving and gets the rpms up she has all the power i could want. Any ideas what could be causing the low end power? I am going to replace my fuel filter and spark plugs and see what happens...they need to be replaced anyways. But I guess if you guys could just start tossing out any idea on why she could be bogging down that would be great. Just start naming anything. I basicly had everything off the car and pluged alot of lines and dont have much for emission left execpt the bac valve and the good old rats nest and solenoid area. Any help would be greatly appreciated.
I am going to drive her a few miles today just to see if maybe she will build the power back. It hasnt been ran since november, so maybe its just not warn back in or something hehe.

actually was thinking about that....but i havnt really had any problems with flooding or starting at all. I would think with low compression it would be a bit more difficult to start and such wouldnt it? idle be a bit more on the shitty side?
it ran fine before i put her away for winter execpt for idle. got my injectors sent out and cleaned...took off all my intake and exhaust and replaced gaskets and such and put it all back together. now no power =/
i had to get new intakes...so i got some used ones which turned out to be jspec. maybe something on how i hooked that all up?

well, I am going to go buy the stuff so i can do the error code check tonight. So I will post what kind of error codes I get and maybe we can figure out the problem from there. Also going to check spark, maybe check timing, the dashpot and tps are correct?

Just take the blue pill..
have you checked to see if your injector plugs are fully connected? sometimes the wires back out of the plug and would cause the symptoms that you described.

That very well could have happened...my plugs were getting pretty rough shape. I will look into it after I do a few other things first and double check stuff.

Well I checked for errrors and got nothing. Did a compression check and she is still very strong. I am leading towards the injectors then. Either connectors poped off a bit or just something isnt right. maybe i hooked up the resisters wrong on the secondary injector wires for the 680cc injectors.
I am curious if anyone knows if I will be running lean uptop if I put the old injectors in? I have a 2.5 inch straight pipe with a little tip at the end. and i have a cone filter intake. Walboro 255lph fuel pump
Also could I maybe be running so rich right now with the 680cc secondary injectors that it would be causing the car to bog down so much? I have a SAFC but havnt installed yet.

yeah to bad the dyno is a good 3hrs away ahah
would running that setup without a safc...make it very low on power. I mean I can barely even get going in 1st gear the power is soooo bad. it bogs down to like 400rpms and just barely makes it way back up.

Dude you have a big fuel pump and no S-AFC! The problem is right in front of you. The fuel pump is cramming more fuel into the engine than it can efficiently burn. Get an S-AFC...problem solved.

My rebuild is doing the same thing. No low end torque.
I figure one of my injectors is sticking cause my front plugs are clean and soaked when I pull them.
Does anybody recall what the little plastic cap on the end of the injector is used for... One of mine was cracked and I was told it is just to protect the head of the injector. BUT maybe he was wrong and its leaking in too much fuel into the front chamber

I just think its weird that I would be running so rich. It ran before with the fuel pump. And I thought the 680cc injectors would only mess with the top end?
But I guess the only way to find out is hook up my safc and see what happens.
