i can try the bounce test again - last time i tried i didn't think there was much bounce... when you say "turn the top of the strut- if it turns easily" - how easy is easy? if i put the torque wrench on the upper strut nut the strut just springs around (and back when i let go). do you mean...

hello, i have a '93 850 sedan (135k) with intermittant 'bumpyness' at speed. at times it feels like it has is continuously running over small bumps in the road even though the road is smooth. real bumps in the road seem quite violent to passengers. i was checking the front strut nuts and noticed the...

ok, thanks. i was thinking about becker's tonight and wondering if they bought cars. i'll give them a try tomorrow. i'll check with npr and see if they would take it as a donation. i put an ad on craig's list and someone wanted the tranny (not the car). maybe i can sell the tranny and then the rest....

hello, my 240 got hit and i'm wondering if it is a write-off. turning left onto the road and it got hit by an oncoming car at low speed. the hit was on the driver's rear tire and pushed the car 180 degrees around. the damage is all in the rear drivetrain: the track rod mount (where is mounts to the ...

kevin, i never let my temp gauge go above 3 o'clock before i turned the engine off while i was testing. i don't know i would let it run to 2 o'clock...for long... my ecu would drive the fan when i unplugged the ect sensor and started the engine regardless of the temperature. apparently, this is norm...

just a follow up on this saga. finally got things happy again and i've been driving the car and a/c hard for a couple of days to check. :) 1) it turns out i was low on a/c refrigerant. i jumpered the low pressure sensor and the a/c would run continuously. previously, i mentioned it was cycling from ...

i would summarise that:

1) radiator fan does not appear to respond to high water temp
2) radiator fan does not run and a/c cuts out when a/c reaches high pressure

any ecu experts got any troubleshooting suggestions?

i tested the fi-ecu today in test mode 2 with the engine running. with the ect disconnected (which makes my fan run) i get the right code 1-1-4. with the a/c on (and cycling on and off) a 1-3-4 staggers out, all as expected. while i was there i tried test mode 3 as well. the injectors and the iac bo...

the ign-ecu test in test mode 3 all seem to be fine. no surprises there. i couldn't get the fi-ecu to show any codes in test mode 2. i got the ecu into the test mode (light flashes rapidly) but am a little unsure how to trigger the 'fan on' and 'a/c compressor on' conditions. the a/c and fan don't r...

lee, even if i probe around the ecu's i am not proficient enough to start diagnose the ecu's themselves. thanks for the manual. the best doc i found was 'test with codes'. from that i deduced the layout in the attached pic. i was hoping the ecu's would have some useful self diagnostics. they seem pr...
