Hey out of nowhere today my car started shaking whenever im in acceleration on my 1.5L 96 5Speed Protege....If im in gear and not accelerating it does not shake, but when i hit the gas it starts to shake.....but it doesn't do it in neutral either though. Any ideas? Also when I shift into a gear its like the idle is low...slow to pick up speed... Any ideas? Im hoping its something simple like a plug or wire :-( I know my economy will be horrible but am I good to drive at least?(Of course there will be performance symptoms)

Codes?
What frequency is the vibration?
Does it only happen at certain speeds, as if it only resonates at 30mph and 60mph?1991 Protege LX with GTX swap, DD1990 4WD Protege with GTX swap, Project/garage decoration2006 Mazda 3 with 2.3, Her car1980 Ford F100 Short bed with 300ci 6 cylinder, work truck/home for moss

I will check the air intake tomorrow....ill probably get some new plugs anyway though

If there are no codes and the vibration only happens when the drive train is engaged, then----
But there are codes.
Could be engine misfire. Codes and poor millage seem to point to that. It might not be a bad idea to check the tires for even wear anyway. It's easy to do and it's free.
Get the CEL light off and see what happens.1991 Protege LX with GTX swap, DD1990 4WD Protege with GTX swap, Project/garage decoration2006 Mazda 3 with 2.3, Her car1980 Ford F100 Short bed with 300ci 6 cylinder, work truck/home for moss

Okay so no new codes....so ive kinda narrowed it down.....Its either due to my high idling issue ive been dealing with or clutch/tranny related.....my car idles really high....and im hoping that will go away if i clean my IAC/EGR....Would my high idling issue mess with my shifting? And if its clutch/tranny related, how do i know if my clutch is slipping or my tranny is going

WAIT A MINUTE....Im new to this stuff but doing research....i thought my car was just idling loud but then i saw a youtube video of a guy who said his tranny was making a noise and kind of sounded similar to mine....I HATE that this car doesnt have RPM meter....How do I know that its not an IDLING Engine sound or if its a Transmission sound?

If the clutch is completely shot you won't be able to shift at all or the engine will surge in RPMs as you accelerate but you won't actually go anywhere...it will act as if it's in neutral.
High idle can be caused by a massive vacuum leak (which is what a stuck IAC acts like) but then it would probably run rough or horrible. The 96s have more vacuum lines than the 97-98 models, and, there's the issue of that large resonator on the back of the intake which people say causes poor operation if it pops off or leaks into the intake.
A transmission sound (like low on gear oil) has more of a whine to it unless there's no oil in which case it will be a grinding noise. It will be consistent and get louder as RPMs increase and *should* sound the same in neutral if there's a defect affecting all gears as you are thinking.
Personally with your description of it vibrating it sound more like a big vacuum leak to me. Again, recheck your air intake hose thoroughly...cracks and breaks sometimes are hard to spot.

BTW you need a special security T-25 bit to take the IAC off (it's a normal torx-25 with a hole in the center). Autozone sells a 100 piece Great Neck bit set in a blue plastic shell for $8.99 that includes this and a bunch of other security bits.

I also reused the gasket when I cleaned my EGR valve. My throttle body gasket has a small tear in it, and it tore apart when I took the throttle body off. I put the gasket back on with some gasket maker gunk and drove to Advance to get a new gasket. The EGR gasket is metal, so you shouldn't have a problem with that.
