Yeah. Good times and bad times but she still been on my side, and treated me better than any girl I tried talking to. Always some dumb shit, but could be much much MUCH worse. Plug wise at least it didn't slap any pistons. When I had the lower plenum off the valves looked normal. I see your point with that, but weird thing is everything timing wise is on point. Me and my friend carlos who is acculy a hcc garage teacher did everything timing wise. Pump, tensioners, belt, pretty much everything except the oil pump o ring and cam seal o rings. They were fine. No leaks whats so ever. One thing I noticed yesterday is it sounds like I have a vacuum leak in the back of the manifold. IDK what it can be. I go to work soon so I will check later with brake cleaner. I hope it's either a plenum gasket, or a worn out hose. I will be like so happy if that's the case. I know a vacuum leak can cause miss in the car. Can this be possible that I damaged the rear lower plenum gasket? What ideas can you guys give me to check this?

I read up and it ended up being for the older Mitsubishi engines, so not needed. Also I replaced the whole distubitor and I'm having the same miss. My cel came on po300 twice before replacing the dizzy. I also cleaned out the fuel injectors, replace the fuel pump assembly, with the filter, cleaned the air filter, and cleaned the maf. Still does it. You could absolutely feel it from the exhaust. My plugs look like the good ones but the tip rings are darker and the tips are alittle more lighter. Just the threads have oil, but none on the tips at all. There is no oil in the spark plug tubes that I can tell and the gaskets look fine. Oh yeah on top of the weirdness my car seems to drive normal. It has hunting idle. It also starts up normal as well. :scratch:

Cleaning the maf might be your problem if you or anyone else has cleaned it before. I know its not supposed to be cleaned atleast not with water CRC maf cleaner or any of that stuff.
More info can be found in the thread "all about our mafs" i think thats what its called. Maybe go about cleaning those spark plug tubes again, and the threads like detter was saying. Im not sure how you would clean the threads though.

Thanks brothers and happy new years by the way to everyone:)
To be honest idk why or even how the hell the plug threads have oil on them, but not on the tips. The spark plug holes are dry and the valve cover o rings are fine. I got 2 dumb question. 1 is it possible even if the valve cover o rings are still good that they can leak a little? 2 are there spark plug tubes o rings in the bottom? I heard that most cars have that. You do have a perfect point about the threads and ground. Idk anymore. I love my 3g but it's becoming a royal pain in the ass. Someone tried saying burnt valve or even low compression but I don't think it can be. Still runs fine minus the cel, and jerking once in a blue :happysad:

Happy new years!
Question#1. It may be possible if you used some off brand VC gasket set. If the valve cover itself is bent that could be another way. If the valve cover was ever removed the the plug tube seals are trash(can't use them twice). Good oem VC gasket set with an unbent valve cover tightened down in the proper sequence to the proper specs should never leak. Proper sequence and proper torque spec on valve cover is a must.

Question#2. Are you asking if there are plug tube seals in the bottom of the heads? If so the answer is no.

for the first question I don't think it is an off brand valve cover gasket even though I see slight oil around them. But nothing bad at all. This is only once in a blue. But like I said there is no oil in the spark plug tubes at all. Also I took the plugs out again, no oil on the threads this time maybe cuz the anti seze. Idk. The tip again is white and lean, and around the ring is black. No oil deposits whats so ever, and this is all the spark plugs. New fuel pump assembly, dizzy assembly, plugs, wires, cleaned out the injectors, fuel treatment, oil change every oil change, and cleaned out the maf, and air filter. No air leaks that I can tell but I can be wrong :dunno:

Also 2 thank's for the answer. Just wanted to be sure :lol:

But how did you clean the maf? You keep saying you cleaned it like its a good thing.. if you cleaned it with completely dry compressed air that might not have been bad or if you cleaned just things out of the honeycomb by hand with something completely dry then your probably fine. Bit you didnt say anything about my comment earlier where i said CLEANING THE MAF IS BAD (atleast with chemical cleaners or water). So im just curious to get your comment on that, and how you cleaned it. Not sure if you read that part of my post since it wasnt mentioned in your next post.

Heres the link to all the info on the maf if you didnt read this already, where it mentions MAF CANNOT BE CLEANED.

Yeah. My fault. I was half asleep when I parshley answered your question. I used maf cleaner from advance auto parts, then let it air dry before I put it in. Here's a picture of the cleaner I used.
Also two dumb question. Sorry if I didn't search, but I am at work, and typing on my phone. L.O.L!!! If I unplug the maf and the idle goes around 1500rpm, and doesn't die, does that mean the maf is good? Also another question. If I unplug my cps, and my car dies does that mean it's good or bad?

i think i may have found the reasoning behind your misfire. silvertune made a statement on his pnp thread about stock or shitty timing belts. i think yours may have stretched under throttle and is throwing it slightly out of time.
id pull the covers and line up the crank timing marks and see where the top lines up. could be that. its happened to me on my crv i had. that would solve for lost compression, excessive oil, alight misfire, if youve done the full tuneup, id seriously look into it. Even if its just to check your belts, and double check everything.

Funny thing about that. I'm acculy using a dayco timing belt kit. So quality is really good, and not shit. Bad news is I think I have a burnt valve. There is a test where if you put a dollar bill behind the exhaust and it feels like it sucks in then out that it could be a burn't valve. FUCK MY LIFE!!! :scream:
Car when warmed up , and long drives idles like shit and will die once in a blue, but starts up when I turn it over. I'm also having another problem where my gas guage now doesn't work. I was alittle over 1/2 and light came on. I put 10 bucks into it, and never changed. I'm trying to trade my ride, and I think she doesn't want me to let her go. I put a carquest fuel pump assembley in. As in the whole assembly. Float, sensor, filter, pump, etc. I don't know what the hell b going on with this thing. I been having dumb shit with this thing for the last few weeks ever since that night with my sparkplug. I also have a weird thing going on I just notice. When I take my pcv valve off smoke comes out. When I take the oil cap off same thing, but yet it doesn't feel like it's blowing out. :dunno:

I'm probly not going to sell her. I'm going to do a compression test and prey to god that the rings are good, and I can just do head work. Worse case senerio just drive with this engine, get a 3.5, and build it on the side to slap in if anything.
