Howdy folks,
I'm posting this question on behalf of my dad who is still very much afraid of his computer. He's got a 1998 S70GLT. I've attempted to Google for any obvious answers to these questions or for an S70 FAQ but couldn't find anything obviously relevant. Three questions:
- My dad's fond of doing his own repairs, but has found the Chilton shop manuals not specific and helpful enough. Are there any other recommendations for reasonably-priced shop manuals?
- Recently, a mechanic inspected some of the output from the on-board systems and suggested his fuel's running a little rich and he might need to replace his O2 sensor. Apparently, however, there are actually two of them. The car has about 147K miles on it. Should he replace both O2 sensors as a matter of preventive maintenace or just one? If just one, which?
And the fun one:
- Occasionally, when he starts the car up, the environmental system starts working for less than a second, then completely stops and both the 'recirculate' button light (which is orange) and the 'off' button light (which is also orange) start blinking. This *NEVER* happens in the morning when he first starts the car, and it *NEVER* happens mid-drive -- only when he starts the car up (or just turns the key to the 'on' position). Turning the car off and on again, several times, often clears this, but sometimes not. Any ideas?
Thanks for any suggestions anyone may be able to come up with,
-roy
