I recently purchased a 1988 9k with 176,000+ miles on it. Overall the car drives great and has a very small list of to dos given what I paid for it.

The most troublesome issue I am facing right now is a idle/cold start issue that does not seem to cure with the normal remedy's. So far I have...

-replaced most vacuum lines to throttle body with HPS silicone vacuum lines
-removed, cleaned and reassembled throttle body and MAF. For what it's worth both were relatively clean.
-disconnected battery to give ECU a chance to reset.

Went ahead and took a short video to further help diagnose this issue. At 0:23 seconds I press the gas and notice a loss in RPMS before response.

(I currently have my third brake light unplugged (hence the light out alarm on dash) and am aware of the abs fault on dash as well)

Thanks in advance guys!

Back in the day MAF's were hated things.
All my saabs that I owned with those required replacements..
Your stated issues certainly remind me of the classic failing MAF symptoms.

this is what was highly recommended in the C900 forum as well. I have been updated that thread however I’ve confirmed my vacuum is good (added a more informative vacuum boost gauge and confirms vacuum is in the 18Hg range). Trying to source a decently priced OEM MAF however in the mean time also confirming ignition system is in good order as well.

Just an update for anyone else with a similar issue it was indeed a faulty MAF - did not catch it at first but the MAF in my 9K was an aftermarket/3rd party and was not up to par - ordered a MAF ended in Bosch part # 005 and is working great so far. Will update if anything changes!
