Did replace the battery this past weekend. It was 7 years & a month in the vehicle, about 8 years old from the manufacture date. Had the store bench check it anyway, and it was good but at about 60%...

Finally replaced the after-CAT A/F sensors last night. Looks a little cleaner, since the old ones were drenched in oil from the now-repaired valve cover leak. However, it didn't change a darned thing...

I can totally buy that. Still, incredibly weird I was only getting a misfire on 5, until I swapped the 1 & 3 coils and then got "misfires" on 1, 3, and 5. Then, swapped the 1 & 3 back and continued...

Installed six brand new Bosch coils last night. It sure smoothed out the idle, with a very steady and smooth exhaust stream coming out the tailpipe. No evidence of a misfire at all now, except that...

All this has totally messed with my motivation. Was gonna tackle at least one of the DISAs this morning. Now I'm not so sure I should yet. It definitely idles and runs like it has multiple misfires...

OK, officially about to scream! I'd already swapped coils 1 & 5, and the P0305 (cylinder 5 misfire) didn't move. So, swapped coils 1 & 3 about 30 minutes ago, to see if maybe the issue was with...

Yes I've read several things and watched a few youtubes on it. It makes a lot of sense to me that it could be the culprit, so much so that I just went ahead and ordered the DISAs. I can envision when...

The saga continues. Replaced all 6 spark plugs last night. Sure fired off briskly, but took it out for a short spin and after a couple of minutes, it ran like the same old crap. Cleared all the codes...

Isarkisov, did you replace both DISAs, or just the top one? Did you have to pull the intake manifold to do the lower one, if you did it? What about the throttle body, as you mentioned? Thanks

A side thought: I also have a very annoying oil leak. It's bad enough that it runs down onto the CATs and makes a very bad smell which really ticks off the wife. I have purchased the valve cover...

Wow, you sound that convinced. Guess I'll have to go clean a pair of VANOS. Thanks. I'd have done it long ago if I'd realized how simple it would be (I think).

Agree that counterfeit parts are a...

Okay, figured out this VANOS thing, thanks to a couple of youtubes. Dual VANOS units, mounted in the front of the engine. I can see them. Kinda ups the ante $$-wise, since there are 2 of them. I'll...

Well, got the exhaust flanges lined up and bolted together Thursday night, with the help of a large metal hose clamp and a stubby combination wrench. No apparent exhaust leaks, YAY! Unfortunately,...

Yes, I did replace them because of the code, but more to the point, the poor performance. I am definitely saving the OEM CATs, fully aware that the problem may be something else. I have new A/F and...

It does have a nice rumble to it, without the muffler system attached, LOL. The wife not happy about it, though. Go figure!

Haven't been able to drive it around yet because of that. I'm anxious...

I am thinking this is not likely an injector issue, unless injectors have been known to get sluggish after an engine warms up.

I have a vacuum gage, if I can find a way to plug it in. Not sure if...
