New problem started about two months ago: gas gauge suddenly starts reading about 3 gallons under. Last 3 tanks I've filled it and gauge will only go up to about 15 gallons. Seems to read linear all the way down, haven't drained it to the point of turning on the light.

Did not do any work on the ...

6 weeks out and car is still running great. The wire short definitely was the problem. Still can't figure out how the wiring got damaged. The engine wiring loom is totally encased in a thick black plastic cover from the ECM box all the way down and across the cross member, and the damage was inside ...

Typed up a long explanation, attached photos, went to preview, and somehow lost the whole post.

Pointing to vacuum leaks is not the panacea for every ailment with these cars.

It appears that Bosch manufactured MAF sensors have become unavailable for my 1998s. Original Volvo OEM still available if you want to shell out $360 (at a reasonable website -- another site wants $812.00!!!). What are folks' opinions on the next best replacement MAF in 2026?

When you're dealing with a dead-end hole, and presuming you don't have a lot of extra depth to play with, you should have two taps to do the job properly, if not three. The taper tap is the starting tap to get the threads started, and can be used to cut thread for as deep as the tap will go. There ...

Here's another tidbit of information. IPD strongly suggested to me that I don't bother finding replacement boots to fit my mystery axle in my 98 V70 T5 manual. They said the aftermarket replacements from Autozone are affordable and seem to hold up. The manual replacement axle showed as unavailable ...

I've searched all posts in this forum with "seats" in the subject line and found a few queries, but cannot find a clear answer. I just purchased a 1997 S90 from the original owner with 130k miles on it. Really don't like the soft seats, much prefer the seats in our two 1998 70s. I have plenty of 70 ...
