Help me save Christmas! 98 V70 no start/rough start Topic is solved

If the 99+ cars have an immobilizer what is the early system called? My 850 definitely has a security system, it's just not using a chipped key.

The chip is molded into the plastic on the keys.

They had additional security systems that you could order, called "Guard 2" or sthg. similar. They were different than the chipped key immobilizers. I think they worked with a fob like remote thing.

. .. somebody else came here to the forum and said they have a 1998 v70 and they have a transponder so i started wondering if some cars could actually have one. Then i read that maybe only in the UK not in the US ...

In the European market Volvo released things a year earlier. Their first V70 in the Euro market was a 1997 V70, the same car/model was released in. the US market as a 98 V70. Etc. So a 98 V70 in Europe matches to a 99 V70 in the US market.

Hi,

Oh that's very interesting. Yet another oddity from Volvo. No wonder why these cars are so confusing.

So that also explains why when i look on the web for a transponder key for Volvo 1998 v70 i only see 1999 v70's come up.
So i actually have a 1997 car design that's amazing.

I also read a bit about the transponder chips they are not that complicated. I also saw a way to cheat the system, by taking the transponder out of one of your keys and mounting it close to the ignition key hole in your car so when you go to start it the car always sees a transponder.
This way you can buy keys without transponders and just get them cut without any programming. Dont know if it works with every car though.

All Right, came back from Vermont. Spent a lot of quality time with the inlaws, and went winter backpacking to a cabin in the Merck Forest, which was fantastic. Honda failed Vermont state inspection for surface rust one brake disc, which is insane. Next time remind me to use scotch brite beforehand, geez. Shop knows it is a $500 metal ticket so they will fail cars all day for this garbage. They suggested to put calipers in it too. Anyway..

I put in the new Cardone MAF sensor. In the box marked Cardone 74-10044 was a remanufactured Bosch sensor, 0-280-217-107. I was a little dubious considering how cheap it was from Rockauto.

BUT

It runs great! Better than it has in a while, I think. Still no codes other than the evap small leak it has had for a while.

I let it run for 40 minutes or something, got it good and warm, and then changed the oil. Thought the oil might have some gas in it from all that rich running, plus it was sorta due for a change anyhow.

MAF numbers are much more reasonable now. Around 3.5-4.5g/s idling. At cold start it runs like 4g/s and then when it gets warm it goes down to the mid 3s, and then up to 4 when you put the automatic into gear because of the increased load! As opposed to what, 40-150 from before!! I guess I now know what good numbers are. I'm guessing it was basically just pegged at 5V the whole time, and that's the way it failed. Not sure if that's unusual or what. Maybe I'll dig into the circuitry inside and see if it can be repaired. The document here provides some interesting insight into what could have gone wrong electronically.

Now, Volvo buddies, go forth and buy ALL of the reman Cardone MAFs from Rockauto before they disappear. I know I am going to buy a spare!

Glad that mostly worked out. What does $500 metal ticket mean? Do you get inspected every time you enter Vermont?

Nah, state vehicle inspection is ostensibly for safety and emissions. Having lived in states where it's required and other states where it's not, I don't think it helps anything, except business for mechanics and dealers. It is supposed to get done once a year, at basically any privately-owned shop. The Honda's state inspection was due in December so I thought I'd try it while I was there. You make an appointment and give them the keys and they do a checklist and put a sticker on the windshield if it passes. A cop can stop you for an out-of-date inspection sticker and issue a failed-inspection ticket, but that's not what I was talking about. I think those tickets are $300 or so, not cheap.

A "metal ticket" is apparently new england mechanic's slang for a bill involving basic parts-changing. The shops love to fail your inspection for stupid cheap stuff that they can charge a lot to change, like brake discs. In my opinion it is a conflict of interest. They have the power to fail your car and then if you're a normal person who doesn't do their own work, you will probably just sigh and pay them to do whatever they say is necessary for the car to pass. Dealers are famous for failing cars they'd like in trade. So this place gave me an estimate for $500 to change the brake discs and pads in order to pass the inspection and get my sticker on the Honda. So now I've got to change the discs and pads on the Honda and bring it back to the same shop to get the inspection sticker on the windshield. The shop that failed me will do it again for free if I have fixed everything they have quoted me for. I'll have to drive up in the dark and not get stopped by any cops because my inspection sticker is out of date as of today. It's just stupid.

Well known here too. We don't have an annual inspection, but we have to get an insurance inspection done on any car you own over 10 years old, some companies are 12 and some 15. Mostly not too horrid or expensive. That inspection makes no sense because if I then keep the same insurance company for 10 years it does not need inspected again. If I change company then I have to have it inspected again even if it is 6 months after the last??? I have taken my 'R' off the road for around 6 months but as I have kept it on 'Park up' insurance no inspection needed in the spring again.

The there is the 'Out-of-Province' inspection. There is some validity on this as it checks Vin# and other details to try to reduce the chance of stolen cars transferring provinces. The real money maker is there are limited places that do it that are all licensed by the Province and repairs have to be made there. Inspection price is high and mostly useless. No emissions check though.

I actually did buy one months ago. It was garbage. I was going to try to return it, but never got around to it. It wasn't fully seated in the housing, and I pulled the screws and found a stripped hole. I swapped it into my original 850's housing. It didn't work... it read way high.

Done 250 miles so far with the Cardone MAF. Car gets much better mileage, it seems!!

Smells a little like sulfur on startup. I'm guessing that's from overloading the cat with the overrich mixture while the MAF was malfunctioning or disconnected. Hopefully that goes away. Doesn't seem like the cat is plugged at all.

Maybe I'll swap in the other Cardone MAF I bought and see if it's just as good!
