96 SE-R - Lack of power and likes to rev on it's own to 4k...
I posted this in chassis specific originally but it seems dead in there so I'm hoping for a better response here. Mods, feel free to delete the thread in 200SX SE-R, this is probably better suited for this subforum anyways.
So my free 96 SE-R is running again. I had to pull the starter off the free B13 and I had a new ebay fuel pump for the B13 that I also used (which does NOT fit in the b14 fuel pump housing). Siphoned out the old gas, added fresh gas and stabil. It wouldn't start saturday after doing that work but started fine on sunday, go figure.
Anyways, it feels *REALLY* slow. I don't mean normal SE-R slow, I mean worse than a Geo Metro slow. It also likes to rev on it's own up to 3,500-4,000RPM. If you pull the throttle cable it will often just sit there after releasing the throttle. It doesn't rev all that freely either, seems to struggle to rev up.
Here's a video with it running and hanging, especially at the end: 1996 200SX SE-R issues - YouTube
Now the cam timing could be off, but research by a buddy of mine with an SE-R led to potential MAF and/or vacuum line issues. The car has sat for years, so vacuum lines are quite possibly dry rotted away and the maf is quite possibly dirty/broken. I'm going to try the MAF off his 97 and see if that helps and start tracking down vacuum lines but I figured I'd post here and see if anyone had any other ideas.
Oh and no CEL, but I learned later that the previous owner pulled the CEL bulb due to some issue with early Fidanza flywheels or something causing the light to come on. I don't think the 96 would have the bulb on the ECU as well to check codes so I may have to reinstall the bulb to check.
Any other ideas?
Thanks!
