Trying to figure out which way I should go.
Should I buy the USB cable from here:
http://aldlcable.com/Or should I build my own serial cable and get a USB to rs232 converter? Directions to DIY here:
http://winaldl.joby.se/aldlcable.htmI have a win7 laptop with only USB ports. I'm ok with trying to build a cable and using an adapter if it will work and be cheaper. Didn't know if anyone here has experience with USB ports and winaldl.
My car seems to be running well, the idle is sorted right out and is rock solid. VSS has been replaced, tranny fluid flushed and new synchromesh in it: tranny is shifting ok (thank god) and speedo/odo are fully operational again.
This weekend I got out to go for a cruise in the nice weather. Now it seems after I've been driving for a while and when it gets nice and warm it will start to stumble/buck/surge, etc. No SES light. There are codes but they're still from when I put the top end back together a few weeks ago and had to adjust the throttle body back down and from when the VSS went. Codes are for a high idle and VSS. The oddball code was a O2 high voltage/lean code. I'm not sure if that has something to do with the way the ECM was managing fuel when I was driving on the highway and the VSS broke. I saw that code when scanning it after the sensor broke.
Today I swapped in a spare ICM I had as a shot in the dark and it drove pretty much the exact same as the original one that I had. Pretty much fine when warming up and after 20 minutes or so, maybe sooner after cruising on the highway it will start bucking. Idle is perfect whether it's bucking or not, i.e. it starts bucking and I have to push in the clutch and it will idle perfect while coasting or if I stop.
My first step is going to be clearing the ECM and having it re-learn itself after a drive or two to see what codes are really there now. I'm mainly interested to see if the 02/lean code returns. Then I figured I would try connecting to the computer to see if I can figure anything out with winaldl. I've never done anything like this before, but I don't want to be making guesses and just throwing money at the car.
It's a joy to drive, until the bucking kicks in.
It was doing this last fall before I did the tune up over the winter while re-finishing the plenum and valve covers. It is running much better, but still bucking.
Any advice on the ALDL setup with USB would be appreciated, or any advice with my issue in general.
I thought I should have picked up that 02 sensor I saw at the swap meet.
Thanks,
Ryan
