My 95 has a bigger problem than I thought. Interesting Read Here

After reading here and on the other forum website, I though my problem with sputtering, missing and difficulty in getting my car to move at lower speeds was going to be solved easily. The car only does this when it tries to take off--under heavier load. After you get passed 40 mph, or so, it almost completely stops. Well, it does it but way, way less. It's so strange since at idle it sounds like a dream. I thought that since I had a P0100 code (MAF Circuit Malfunction) that that would clear the problem. Before I dealt with that or the EGR, as I read, I had to fix a problem I saw with this just bought car: I had to reconnect a bunch of vacuum hoses that were incorrectly connected and others that weren't connected at all to get that out of the way. In the process, I noticed one of the hoses could not be reconnected because the place to connect it was broken off. The pieace where the hose went was on the part called the resonance chamber. It's that black plastic reservoir looking part right before the firewall at the top of the engine. It connects to the intake. Two hoses go into it but only one could be connected due to the break I mentioned. I got one from a junk car. When I removed mine, oil poured out of it. I asked a mechanic/neighbor what he thought. He said that oil is probably passing through the piston rings. He asked me to remove the oil cap and if compression was coming out of there then that was proof the engine was in bad shape. He also said I could check for wet spark plugs. I only checked the oil cap but that was all I needed. Compression was coming out of there and the air that came out was spitting sprinkles of oil all over me and the engine. What I thought might be an easy fit may require a whole new engine. I will post this on the "other" forum website too. It's a 95 automatic with the 1.5L engine.

uhhh ALL import engines have crazy blow by at idle... its NORMAL... start reving up the engine with the oil cap off and if it stops doing it, then your engine is fine

But then how do you explain all that oil in the resonance chamber? The car I took the replacement resonance chamber off was at the junkyard due to a crash and not engine trouble. That car's resonance chamber was completely dry like it's supposed to be. There was not a drop of oil in there. That's only supposed to take in vacuum air and gases. What's your take on that?

did you ever replace your PCV valve?

I just got the car and bought it knowing that it was running bad. I don't recall if I checked the PCV valve but I'm almost sure I did. I did so much hose connecting and re-routing that I must have checked it. I will double check that. Would that bring that much oil into the vacuum system?

Hell my car spits out oil like crazy if I remove the oil cap while the engine is at idle.........And I only have 94000 miles.........That particular theory is just alittle bit inaccurate dude.

I will re-post this everywhere I saw a post with people having similar problems: Ok, upon turning the car on, my car would sputter, try to stall, sometimes just turn off, etc. It would then get better as the car picked up speed. As soon as I had to stop and go again it would do it again. I had to wave cars on. I put a computer scanner to the connector to see why the Check Engine Light was on and it showed P0100. That code means MAF Circuit Malfunction. If you have that code and those same symptoms, my friend, you have just found the answer. It is the Mass Air Flow sensor. I replaced it and the problem went away 100%. It is a dealer only part and costs over $200 so look for a used one. I know this is not going to help those that don't get the code but it's going to help someone that has the same problem. The little filament ,or whatever it is, was completely missing from the very center of the sensor. It's like a little "feeler" that senses the air and sends the info to the computer. The fact that the computer would not put some default adjustment really annoys me. The car should not become almost undriveable. No more Check Engine Light (CEL).
