Tune up, misfire, stalling, Tune up? 1998 v70

Post by **MrAl** » 01 Dec 2022, 09:20

Hello there,

I have been having some stalling problems and traced the problem to the fuel pump relay, but found out today that was only part of the problem. The other problem was cylinder #3 was misfiring, and finally got a code on the OBDII meter.

What i found out was the ignition coil wire was half way off. I noticed it had a lighter space beyond the rubber boot and when it pressed it it slide back on fully, and that was a full 1/2 inch i think. That's a lot of the way off i think. Now that it is on, there is no misfire.

But it has been a long time since a tune up. At least 6 years. You think i should replace the wires and spark plugs and distributer, and is that enough or should something else be replaced too for a tune up?
Also for any parts, what would be the best place to get good parts? Or a good name, like Bosch ?

Thanks for any ideas or suggestions.

I would at first, control the spark plugs and electrode spacing. If you've never replace the ignition (ignition wire harness) and distributor, it could be the right moment. Based in France, i don't know the right place to order these parts in Us. Prefer OEM quality, BERU (not sure BERU is OEM, but it's a good quality to me) for ignition coil, and ignition wire harness BOSCH for example.

Here's the llink to Skandix catalog. It may be helpful to search parts and build a budget.

If the wires are 6 years old and Bougicord then don't replace them - they should be fine. For Bougicord wires, whether the ones that came from the factory or if someone replaced with the same Bougicord manufacturer later on, have a date code on them. Check the date code. I don't think you can get Bougicord any more, I haven't checked recently.

Cap and rotor replace in the 50k - 100k window. Bosch only on those parts.

Spark plugs replace more frequently but it depends on what you have in there.

Hi,

Oh ok well unfortunately i dont know the make of the wires at this point because they came with the car. So let's say i have to get a new set, you have any recommendation there, that are obtainable in say a few days or so? I didnt want to take the car out again until i get the new parts on.

Oh ok Bosch i was thinking that too but i never know with this car

Yeah spark plugs over 6 years old too not sure what kind they are either yet. I am not even sure how to get to them. Looks like there is some kind of cover over them. I'll have to check the web for how to get that off first.

Thank you.

Bougicord are still available, but not from Volvo. FCP I think had them on back order a few months ago, but I got a set on sale at IPD.

Bosch for cap and rotor, but make sure you get them from a good supplier so are not fakes.

Spark plugs again I prefer Bosch (OEM) or Volvo's own gapped to 0.028".

You run low miles per year, and ignition parts fail on use, not on time.

But.. you don’t want plugs sitting in an engine for 6 years. Just put a new set if plugs in. Bosch for about $20, Volvo for $50 from FCP

Oh yeah i see some plugs gapped now for 0.044 and 0.030 and 0.028 that's interesting i didnt know they sold them gapped now.
Yeah im going after the 0.028 that's what i thought thanks for verifying that now i dont have to ask

I got some anti seize for the plugs but not sure how to apply it. I used to use a couple drops of oil long time ago but then i saw Robert's video on changing the plugs and he uses anti seize so i got some. Never used it before now so not sure how to apply it. Any ideas?

Ok swapping them out within the next few days or so.

But do you know anything about this anti seize stuff? I got some now in a small tube and want to use it on the plug threads as per Roberts video. Never used it though i used to use a couple drops of oil long time ago, but now id like to use the anti seize stuff.
Not sure how to apply it yet, like all over the threads or just a little at the end of the threads.

I also see many people not using a torque wrench. I never used one either didnt have any problems. Any recommendation there?

I use the nickel or aluminum stuff from Permatex. Just a light swipe on the threads , keep it away from the electrodes. I you hav oil in the spark plug hole you can skip it. You don’t need a torque wrench on a washered plug, just take it down until the washer hits, then about a 1/4 turn more with a 12 inch ratchet handle. Too loose is better than too tight.

One if the problems of the cool latest spark plug tip metal (Cu , then W, then Pt, then Ir) giving life up to 100k now….is that the threads are still aluminum head- steel thread. After 100k miles and 8 years of being married , your cheap spark plug bill quickly evaporates and condenses as a machine shop bill for galled threads. Of course, that’s the next owners problem, on average. I don’t even want to gon 4 years on my heavily used cars, so I stick with standard Cu electrode plugs in Volvo brand from FCP on 1-3 year intervals depending on car usage

Less is more with thread antiseize. There isn’t a lot of space in the threads so a swipe where the threads start will grease the whole thread, just 2-3 threads is fine on a plug
