I don't know how else to describe it. I started my car up with morning it was covered in frost. I let it warm up for like 15 minutes while I was looking for my dress shoes. I came back out and the car was just about to operating temps and most of the frost was starting to turn into water and run off. Hopping in I noticed the car was a bit like being in a old American car with the slight rock back and forth. I was like maybe it just needs to shake the cobwebs out. So I started driving. I quickly noticed the engine on acceleration sounded like a semi's j break. It didn't make a sound when I completely lifted off the gas or at idle, but the idea was still shaking. It idled perfect at 900 rpm the whole time. It only sounds horrible when the throttle is engaged. Also the back fire on down shifts where much louder. I don't know if it's a misfire or an EGR valve. I Though maybe a little water at first but after an hour both ways driving it didn't go away. If anyone has any tips or tricks it be great. Also it's a 95' 1.8L.
Engine sounds like jake break..

Misfire would make your car do those things. Did you even check anything?

sounds like one of your plugs isn't firing. replace spark plugs, try it again, replace wires get back to us. can't really describe to you the sound of a plug not firing since my exhaust is different, but its usually a very low deep tone and sounds really odd, like a v8 or v6.

Is a plug loose? A jake brake is very loud, if it's sounding that awful a plug could have worked loose.
I double checked everything. The first plug wire was easy to pull off. I wiped the lip of the plug wire and reinstalled it. it's tougher to get off but not quite as suctioned as the rest. It's on there snug though. I put my hand down to the exhuast to check the smell. Not only did it straight **** on me but it's got a faint petrol smell like it wasn't burn. The smell was strong enough to give me a headack after a few sniffs. Heres a picture of the discharge. I rubbed it around some and it turned clear like it was some kind of mud mix.

I also found a unplugged wire. not sure what it goes too. I saw nothing to connect it too

Are these semptoms of a need for new plugs and wires. Excuase my ignorance I've never had a problem like this one.
Also it's a racing beat exhuast. It's fairly beep and loud but not as deep as a v6 more like a SAAB 2.0t note. I was going to make a video but my girlfriend refuses to give me my go pro till christmas and my photo wont pick up the sound.

I'm trying to get ahold of my girlfriends little brother to see if he has my extention. untill then I am unable to check the plug.

That plug is for AC or PS I don't quite remember. So the plug is not your problem but I would start with new plugs. NGKs will probably heal this.

Heh, i ran into some bad plug wires on my car last night.
Sounded REALLY cool when spark started breaking up around 12psi.

oh, not particularly indicative of anything. spark plugs are cheap, NGKs are like a dollar a piece at autozone. go pick up a set and replace them. Do you know when the last time they were replaced?
Also, the wires may seem ok, but they get done quickly. electrical resistance is directly tied with temperature.

Nah, I just bought the car. I did everything but change the plugs and wires. I'm probably just a bit over reactive to it not being plugs cuase it's new and have that new car sensitivity to things haha. I'll change them out and let everyone know. Thanks again everyone.

You are supposed to change plugs every three oil changes.
Edit: Depending on what plug you buy.

Maybe in the 1950s. Modern platinum and iridium tip plugs are rated at 90k plus miles
