I have replaced evvvvverything it seems. fuel pump, fuel relay, spark plugs, ignition switch, (because it has a hard time s...

ARGH!!!! My volvo is still randomly not starting! I replaced the IAC valve but the weird thing is, is sometimes when I STOP turning the key it will start. Other times it wont at all. I was told it could be the Mass Air Flow System (MAF) but wouldn't that have shown up on the diagnostic? Another thin...

Hmmm Bill, I apparently my boyfriend sprayed it with electrical cleaner and let it try for a bit but no where near an hour. What kind fo problems would I have if it wasnt fully dry? Your comment about that scared me! =( Im taking out the IAC valve this weekend to clean it properly but should I not d...

By the way, the problem I had began with the volvo not starting. LIke yours, it would sometimes start on the second try or not at all. The problem was immediate just like yours, so I suggest it is the IAC valve.

I had problems with my 740 GL regina volvo as well. I replaced fuel pump, fuel filter, spark plugs, battery, and finally the IAC valve. (idle air compressor valve). To check this I went to an auto store where they ran a diagnostic test. I was sick of not knowing for sure the problem. It ran me 90 bu...

Hello whitebrick! For some reason I just saw your message. Sometimes mine get erased as well. I do live in portland, or and took my car to canyon auto repair to do the diagnostic test. I did get a used IAC valve and am glad that I did because comparing the two my old one could blow air through it an...

Hey there! So the final verdict was my IAC valve. I went to a junk yard and bought a used one because since my car is the regina model, it was much more expensive than if it were a bosch. Hopefully some of the things I replaced helped and didnt go to waste! (ie fuel filter, fuel pump, etc.) Anyways,...

So I gave in and took it for a diagnostic test. I came out to be that the IAC valve needs to be replaced and that is why it is having a difficult time starting and idling properly. After I find a part that isnt over 200 I'll replace it and post my results. Thank you everyone

Hi Bill, I went ahead and took it to get a diagnostic test and apparently it is the IAC valve. Thank god I now know what it is so I can replace that. Now I just need to find one that isnt 200 dollars. Once i replace it, I'll give an update. Thank you!

Hello again. I am trying to decide if it is a waste of money to have my car checked by an auto repair place to run a diagnostic test that will check the starter, the parts and electric stuff. Can I check for this all myself or would it be helpful for them to do it and stop randomly replacing parts. ...
