About my SAAB; 1991 9000 Turbo with 170,000 miles. Autobox; stock ECU, BOV, Wastegate; no MBC.
In my attempts to fix the jolting experience known as fuel cutoff I have performed the following work.
After the hose replacements failed to fix the shutoff i found direction/advise in the archives about cleaning the APC valve to try and eliminate overboost.
Read somewhere to check the plugs, as that is sometimes a culpret. WOW :cheesy: I forgot what new plugs felt like, started right up and felt like the problem was gone, found some open road and once again the cutoff was reached.
My next move is new APC valve, I have been avoiding this, but I am coming up empty on other causes. Anyone else know of other posssible culprets?
If the car had done it from day 1 I would not know what i am missing, but I am well aware that a stock 9000 can embarrass a Honda with fart can exhaust and a body kit.:cheesy:
In my attempts to fix the jolting experience known as fuel cutoff I have performed the following work.
- Replaced vacuum hoses with silicon hoses and zip ties just to be safe.
- "Cleaned" the APC valve.
- Put in new NGK spark plugs (BCPR7ES-11) gapped at .9mm
