I bought this 90 for my wife cuz she really likes mine. Problem was it had a bad motor. So I bought a motor and tranny, cuz she wanted a 5 speed swap. I got everything in and running, pretty well.
Today I got it up to running temp and here are the probs I ran into,
1. Fluctuating idle, about 200-500 rpms
2. Running hella rich
3. Motor stalled on me, I tried to crank it over for a little and it wouldnt start. Now the starter wont turn over, doesnt even sound like its getting voltage, I just hear a relay.
Now my thoughts on the fluctuation and richness, is the O2 sensor, but Im not sure because Im used to 4 wire O2's and this has one, I dont if that makes a difference.
I messed with the TPS sensors adjustment and it seemed to smooth out the idle, but theres still a fluctuation and Im still really rich.
I ran out of time tonite so I didnt get to start testing stuff. Im stuck in the house with the kiddo tomorrow, so Im not going to be able to get on it till Tues. Thats why I figured Id ask you guys, so I can get a better idea on what to start on the next time I can get to the shop.
Thanx alot guys
