Saab 9 5 1999

[Darri415]

Hi
So I have a Saab 9 5 and I've recently started having issues with driving it while the car is hot/ heated. I'm not having any water leaks or overheating problems as I have recently had the heater control valve replaced and the top radiator hose. I can start the car up fine and drive it a pretty good distance (probably about 20 mins or so) before the check engine light will begin to flash and the car will sputter like it does not want to go. I have hooked up the obdll monitor only to get the codes p0502, p0300, and p1300. I have tried looking up the codes only to get different answers on what they might actually be. Anyone with similar issues or suggestions as to what may be the problem? Thanks

2001 Aero 125K. At 70MPH, heard pop, loss of power, flashing [COLOR=#67B045 !important]check engine[/COLOR] light. Immediately pulled over and cut engine off; checked oil, coolant and trans fluids-all ok. Started engine, ran ok, I was only a mile from home so I drove home slowly. (Check engine light came on again but was not flashing). Error Code analyzer read "P1300-torque limitation signal low." Looked on line here and read host of expensive repairs might ensue (valve, cat etc). A few people said it might be a vacuum hose, so I started checking there and sure enough, the big, main throttle body hose c-clamp had come loose and the hose had popped off the throttle body. (see photo). Easy fix! [COLOR=#67B045 !important]Lesson[/COLOR] learned; always check the simple stuff first!

As for you other code just Google "Saab 9 5 Code_______ and report back.

P0502 CHECK ENGINE. Cruise control not working. Low engine torque on cars with manual gearbox.
P0300 CHECK ENGINE. Running unevenly and misfiring.
P1300 CHECK ENGINE. Running unevenly and misfiring.
I'm afraid these don't tell you a whole lot.

Actually it does say alot.
FOr the cruise it likely is the ABS module which is easy to remove and send to BBA Reman for 70.00 and they will have it back to you in 5 days.
The others are either a bad DIC which you can get an OEM unit for 150.00 at rock auto. You must get an OEM unit and, or, the Throttle Body clamp is loose or some other vacuum line is split.
