Here's a comparison of the OPParts spark plug wire (black) and the OEM (Bremi) wires (red). Note how the OEM wire has an extra rubber boot. I'm guessing this is a moisture or dust seal?

Update on my P0306 misfire saga: 1. Found and fixed some bad vacuum lines - there's a "T" behind the left side of the intake which was rotted through. Glad to have found and fixed it, but did nothing

Mike, good thinking. Although the PCV / breather valve was not disconnected, it may have been loose. I tightened it and cleaned up the crud, so I'll be able to see if it's leaking going forward.

Mike, are you saying that all of the measurements of the injector resistances are consistent?? That is a good sign for the injectors as a group.? Might be a good idea to check all spark plugs since

Mike, To follow, this camper has sat for a period of time, so you are working through stuff. The best guess I can give you is that the part you speak of that is NLA is not inserted completely into the

Some spilled it there???

2000 Eurovan Camper. I have oily gunk building up in two spots on the engine. 1) The breather / PCV hose which is on the left side of the intake. This makes sense to me, as the purpose of this part is

Hi Mike, You are correct: when the EVC was last driven any substantial distance (back in November) it was basically running fine. Hence my complete surprise when it almost died on the way to get smog

Mike, You don't report a history of failure, because probably when you parked the EV there was no failure.? Please confirm this. The P0300 to me is a random misfire code, so that the ECU reports it

There he go again........

You're right -- that approach works, too. :-) My approach is not to buy stuff I don't know I need. That's why I suggest testing/validating first. And it's rare a single bread crumb leads someone out

I've been going back of archives of this mailing list (back to 2008 when I joined) looking for stories about unusual reasons for misfires. There are quite a few of them! [I have very lightly edited or

Hey hey out there Your over blowing it, l don’t know what you want to prove ? Just get two new plugs and two good wires and try them, ?

Re my previous post re spark plug wire thickness. The 7mm vs 8mm thickness may be nothing at all. Just depends on where these wires are routed. If they're near anything hot like manifolds, then I'd

I like and trust Europarts. No matter, always test spark plug wires for resistance. Don't know anything about OPParts. I'm a bit concerned about the 7mm wires. That may not be the spec for Euro that

Hello, Michael, My replies about the issue were speculative -- obd2 code can lead you down funny rabbit holes. You're correct about the injector ohm test re clogged or fouled. But that test doesn't

Update: I measured the resistance and all 6 injectors were right at 14.8 Ohms, which seems good. This doesn't prove the injectors aren't clogged or fouled, but does point more towards an ignition

Any opinion on these spark plug wires for a 2000 Eurovan? I think the label says "OPParts", which looks like a non OEM $40 set as can be found here:

My 02 threw those same codes found it was a bad MAF. A few bottles HEET run through the system might help.Spencer

You had me at 6mo old gas. If it was ethanol, as most is these days, a little water in there could cause it to separate out. Siphon out some and take a look. Add some ethanol-free premium and good
