Awesome, will complete the tune up hopefully this week when the new wires, cap/rotor and fuel filter come in... fresh oil change will follow. I usually stick with Mobil 1, any objections? Yesterday I took the car out for a 390+ mile cruise/test... city, highway and mountain driving. NEVER skipped a ...

Thanks kcjones. The weather is looking nice the next coming days so a tune up and oil change is definitely in order. Good idea about the fuel filter, that should be a must I would think after seeing how clogged the PTC was, I imagine the fuel filter has not been changed in some time. Do you normally...

I feel like I have taken over this thread, sorry. So I put in the new MAF and tried to clear the code by leaving the + terminal off for 10 minutes or so... the code remained. I drove it for a while and no sign of stalling... a/c on, a/c off... seemed fine. Took it to UhOh Zone and had the codes pull...

Well, since cleaning the PTC the smoking has subsided. First relief there. Another MAF will be here tomorrow and I am REALLY hoping that will rectify the stalling issue. It is very temperature dependent and I am finding it more and more annoying. To me this is really showing it to be the MAF as when...

Hey! I JUST purchased a 1997 850 T5 with 147,000 miles actually. Everything seemed fine, even during the test drives, until I bought it and drove it all day. Thats when the fun started... stalling, hesitation, squealing rear brakes, smoke after hard acceleration. I swear none of this was apparent in...

Whoa! I pulled the intake tube off and removed the PTC... holy crap that thing was full of crud, I used an awl to poke through it and some sensor cleaner to get it thoroughly clean. It was pretty bad, pretty certain it had not been done in a long while, or ever for that matter. Not sure if this is g...

Wonder why I have the security torx, annoying if you ask me... I do have a few bits for those but not that size. When I remove them I am going to replace them with regular torx screws. More to add: Yesterday at a light the car stalled after it dropped below 1k rpm. I had the a/c system running on au...

Thank you kcjones. I will try what you suggested and see what happens. I am going to run a cycle of Seafoam as well... in the fuel and I will do about 6 oz through one of the vacuum lines. I did pull the code and it is directing the problem to the MAF sensor. I tried cleaning it but do not have the ...

Did you ever figure anything out with this issue?

I recently purchased a 1997 850 T5 wagon and I am having the same issues... it is periodic though which is throwing me off. Otherwise it runs awesome... I have not checked the codes yet though.

I am glad I stumbled upon this great forum!

I am a new Volvo owner, just recently purchased a 1997 Volvo T5 wagon and am really excited. I think I got a great deal on it and am really excited to learn more about these awesome cars.
