Hi,
my now very trusty '91 245 turned 193,000 on my birthday (i think we are the same age...) last week. As if to memorialize the event the next morning the dreaded 'check engine light'(re)appeared.

I dropped it off at the expensive but good Volvo shop for diagnosis. I let them know these symptoms:
1) check the codes that triggered the 'check engine light'
2) When gas is low in the tank I can hear the fuel pump very clearly
3) The car sounds different, takes longer to start, or may not start on first turn of the key (sometimes cranking a long time)

What I did *not* tell them because I was worried that I was imagining it/too embarassed:
a) that just a couple of times going uphill on the interstate the car lurched or seemed to have a major 'miss' but then resumed as if nothing had happened
b) I haven't cleaned the flame trap (can't find a picture or instruction in the Haynes. It seems the Volvo equivalent to flossing.
c) That the car needs a really good tune (i.e. I haven't done it yet and I have done 25,000 miles in 13 months, so anything could be up.
d) Faint fuel odor at start up

The diagnosis was:
1) AMM maybe out (quote $350.00 ++ !!)
2) The pre-pump is shot (quote $500++)
3) Oxygen sensor could be iffy

The suggested 'treatment' is reset the light, fill the tank and keep it above half full.

My questions are:
* Do IPD still have rebuilt AMMs
* Can I source the pre-pump and hose easily and do it myself?
* How does the flame trap relate to all this

Apologies for length, looking forward to the reply

thanks
