Car bogging out on rebuild breakin.
The car is a fresh rebuild with around 200 miles on it.
I finally got through all of the error codes from the engine and now I'm confident about "breaking it in"
The car when warm seems to take off and at a moderate to slow rate (for a rebuild I guess) on a level road.
When I have to drive up a hill while stopped at a light the car dosent want to move!
The last time I was caught in that situation I had to rev it upto 3k-rpm and drop the clutch pretty fast in order to prevent hitting the guy behind me.
I thought that reving it up higher at start up that it might help it climb the hill but it did the opposite. The car bogged out and would barely make it upto 30 by the time I made it to the top of the hill.
While driving up a less of an incline I decided to find out what would happen if I pushed the pedal closer to the floor... As I pushed it I was cautious NOT to let the turbo spool but in the end nothing happened. It didnt rev any faster, couldnt hear the turbo, nothing to show me the car had any power at all.
When the car is on a level surface like on a highway it can start and keep up a little lower then average speed. I can also hear the turbo spool a bit if im not careful.
I think the variable resistor is running rich but I dont think that would cause this to happen...
also it was idling fine but ive been noticing now its almost hesitating when its cold ( dropping off and stalling every so often)
P.S. its an 87TII

It now has 370 miles on it and does the same thing. but just recently I was pulling out of a very steep parking lot and I revved it up to 3k, let off the clutch pushed the as and it stalled...Tryed it again and I had the pedal floored and almost the same thing... revs dropped to 200rpms and it barley made it up the hill..
anybody know what might be wrong?

no, 2-stroke is fine, unless you're using a wierd ratio (come to think of it, mine clogged up not long after I started premixing, too...hmmm...) You can get to the pump from the top of the tank, by pulling up the carpet in the back (look in the Haynes or FSM for the right way to get it out)...I didn't have a new filter sock to put on it, so I just cut a small hole in it for a temporary fix...just have to change the high-pressure outlet filter more often, probably...the tank looked amazingly clean for its age, so I'm not too worried about it...

And you don't have to take out the tank if thats what you were asking.
You just take out the fuel pump... Very easy job.
Something to remember when doing this, DISCONNECT THE FRIGGEN BATTERY!
I've seen so many people take out fuel pumps and other electrical stuff near fuel tanks without doing this, it is suicide if you ask me.
One spark = dead.

Odd, it's not your motor,but you've probably guessed that. My rebuild has 230 miles on it, without spooling it pulls pretty stongly, wants to spool up to much on hills though hehe, so I have to take it easy. Infact my rebuild motor is surpisingly strong. I broke traction shifting 1st to second driving gently, made me grin anyway.

I was driving to school today and yet again I make it to a hill. and yet again it starts to slowly bogg down on me. I shift it from 4th going 80 into 3rd and it seems to pull a little harder in 3rd (obviously) but when I put it into 2nd after slowing down even more it dosent have nearly as much kick in 2nd or in 1st...
Actually now that I think of it IF I keep the revs above 3k she can come close to keeping speed but if I downshift and let the revs go below 2.5-3k it boggs out and SLOWLY c..r..a..w..l..s.
Same with start up in first gear.. rev it to 1500 really slow take off 2k starts getting faster and at 3k its pretty much taking off like it should (im just worried about the turbo spooling so I dont let it get too much above 3.5k)
I've also noticed the Power steering cuts out on me from time to time.. at low revs I think its worse. Thought it was low on fluid so I topped it up... seemed to work but now its back to cutting out again...
I also get a small shock from time to time getting out of the car.. bad grounds maybe? I'm going to do 5 grounds on my car to see if it helps... could that be making the car drop off at low end?

with only 200 miles on a rebuild, you're still breaking it in, especially if you used old housings...the compression just isn't there yet, more evident at low rpms...my guess for the day

i understand the breakin part but other people ive talked to about their rebuild have much more pulling power then mine... The housings should be remanufactured cause i got the engine from the dealer..
I checked my throttle cable but its seems like its tightj enough... I need to tune my tps maybe?

The PS cuts out if im on the gas at all. idle it turns fine.
The car now has about 600miles on it but I cant fell any difference in power gain yet.
If there is a load on the car (going uphill) the car will keep its speed then just slowly loose it.
even if I push it to the floor, nothing happends
