'87 TBI 350 Troubles

Jim, you might want to check out 7-zip. It's much better (in my opinion) than WinZip, and it's also free.

Will check that out, thanks!

Did you get it?

 

[Jims86]

yeah its there...been gone all day, be back at the house in about an hour.

 

[Jims86]

ok, 2 things. That 145 blm is really lean....started to run out of the garage, fearing a loud backfire.
and, is ther a way you can take the ALDL cable out of diagnostic mode?
Diag mod commands 1000 or so rpm.
and stop blippin the throttle...just let her idle.
Check the plugs when you get a chance, see if any are fuel fouled.

Maybe you can remove pin a or B from the aldl port. we just need Data.

ok so i tried to pull out pin a from the aldl port and it wont connect to the computer. so i had to reconnect it.

Here is the new file. i didnt have time to check the plugs but they sound fouled. I emailed it to you jim in case you still cant open zip files.

****, ok. We need to find a way to get it out of diagnostic mode. Wher did you get the cable?

Ok, I will call him tomorrow and see if there is a way to do it. Meanwhile, have you checked the timing again with the MSD unhooked?

yep, still at 0* with the esc unplugged, wont even start with the esc plugged in. It will just backfire out the throttle body.

I didn't pull the pin... I cut the wire and it would only connect when the wire comming form the Aldo port was grounded.

Thats wierd. It should still collect Data.
Lets check something here, since your IAC valve is open like 2 barn doors.
Warm her up to op temp, and shut her down.
Ground a and b with a paper clip or jumper wire. Turn the key on, and count 30 seconds. Then unplug the IAC valve, take the jumper out of a and b, and start it and see how it idles. dont hook up the computer to it, the ecm tries to command 1000rpm idle. it should idle pretty low with the iac closed....if it closes at all.
Timing is effected by everything on that engine, and seeing the IAC counts at over 100 is alarming...should be between 20 and 40 at warm idle.

sorry its taken awile for me to do this, I had the flu early on this week and then playing catch-up with school I didnt have time until today.

I did the test just as you said. it idled really low, so im guessing the IAC closed.

The O2 sensor came in on friday so i put that in there. It will start with the ESC plugged in now, but still not run the way it should (same problem as when we started.

Good News! I figured out how to take it out of diagnostics mode(im pretty sure atleast). I emailed the guy that i bought the cable from and he said that i need pull the "B" pin, so I did. Not sure why i didnt think to do that before.

Here is the new tunerpro file with it out of diagnostics mode. i know that it has fouled plugs so ill check them tomarrow. would have check them today but it started to rain again.
