so I made it home....
when it was going into limp mode in the fast lane it was one of these scary moments..especially when you turn your ignition off the lights go off as well !!
anyway the last 200 miles was virtually limp free and my son has been driving it all over and has reported no tcs probs
I noticed when I was almost home it would do it after it had been on full boost for a while ..there would be a hesitation and into limp...
It does not have a map sensor so I guess it is an di/apc ecu
anyone out there with any experience of these ?
The previous owner had fitted champion spark plugs and methinks (wishfully ) that this has caused the problem... however The first thing I did was change the spark plugs to ngk , but the problems persist..
does the ecu store the fault codes and need them cleared before normal operation can be resumed ?
It boost just on the edge of the red and feels a little pedestrian after the aero but it does step off the mark quite quickly
the suspension feels very "planted" and v good for such a high miler although it has had its bushes done according to its history
all in all I think it is a bit of a bargain
I will be taking into my saab specialist to see what tech 11 says (crossing fingers !!)
Although Tech II was only introduced a few years ago, I'm pretty certain it goes back to about 1989. If not, they should still have ISAT which will pull the codes.
LH DI/APC is pretty much like Trionic- indeed it was it's forerunner. The check engine light only illuminates whilst there is a current fault condition IIRC. Once the fault is cleared, "normal service" shoud be resumed, although the codes will be stored until they are cleared.
Unfortunately running on Champions may well have goosed the DI cart. However it's the same as later years so you could swap it from your Aero to start with.
I'm afraid though you could write what I know abotu TCS diagnosis on the back of a (very small) stamp
