OK. Slowly, I have been able to accomplish some work on the car. The car had been very weak, especially under load. it felt like there was a fuel shortage. Under that assumption, the first thing I checked was the fuel delivery system.
I removed the fuel pump relay and jumped it per instructions and tons of fuel came out - good!
[Note: I didn't measure the rate of flow yet per the bosch manual instruction.]
To be safe, i bought and installed a new fuel pump relay.
In that process, I found a HUGE gaping hole in the intake boot - replaced it. (Strange, b/c I thought i had already replaced it.)
The boot between the plenum and the head(?) has no visible holes, but has not been replaced for sure. Can this be done w/o having to remove anything major? I have a new one waiting to go in.
Checked spark plugs (still look decent with <1000mi - some dry carbon on them) and plug gaps (were ~.35 - so regapped to ~.30).
There still seems to be a flat spot in the mid-range (~2500-3200rpm) as I feel a slight, but noticable surge of power regained after ~3200rpm. There is one problem, though... I'm so used to driving the e30 that I might just be expecting more. The only way I can think of really testing the power is to time my 0-60 and compare to stock values.
Any ideas here?
