I have a 1995 850 GLT and I have loved driving it sence the day I got it. I have not had one problem until now. Now I am having a few problems that I can not quite figure out. My first problem when I drive my car it will not turn over 2000 RPM when you start out. I have checked the code and I got codes in socket A7 - 1,1,3 - Fuel Gauge Sender Unit Open Circuit, 1,2,1, - Tempature Signal interval too short, 1,2,2 - Tempature Signal interval too long, 1,3,2 - No RPM sensor signal. I also get additiional codes in socket B2 - 1,2,2 - I do not know what this means & socket A3 - 2,1,3 - Left Rear Wheel Sensor, no signal moving off. I have the Haynes repair manual and it tells me what the codes are but not how to check them. I would appreciate any help I can get. I would like to do the work my self if possible, but please let me know if this is somthing I sould take to the dealer. Thank you in advance.
