Did my engine pop?
Think my engine may have popped. You guys tell me what you think?
Well, I was driving out to lunch. It was a nice open road and I decided to pass someone so I did a quick WOT in 3rd gear. After I let off the gas I look down at my gauge cluster and notice my tach is reading at zero at my dash lights are on. I realized that my engine was off. At this point I was still coasting at about 60 MPH, so I popped it in gear and popped the clutch while I was coasting to get it started again. Then I come up to a turn and press the clutch down and notice the engine wants to die again. I finsh the turn quickly, let the clutch out and get going again. At this point I decide tha I should skip lunch and get my car home. so I get on the free way and notice I have very litle power. I still get a little power, but even if I boost to 10 psi its pretty weak. After I get off the freeway and get to some stop lights I notice that half the time if I let it idle it'll be really rough and bouncy, other times it'll idle ok. So the rest of the way home I keep my foot on the gas to keep it form dieing. Twice more on the way home I had to pop the clutch while I was coasting to get the car started again. I finally got it home in my garage and wanted to see how it idled. It idled rough and the vacumn was bounceing rapidly between 10 and 8 inHg.
Does it sound like I popped my engine or am I jumping to conclusions? Is there something simplier I should look into as well?

only one way to find out for sure...COMRESSION TEST TIME!

sounds like your engine is gone but do like someone else already mentioned and check your map sensor tube. Mine slipped off once and my car acted just like you are describing. I was convinced my engine was done. Good luck.

What you describe is exactly what has happened to me in the past. What is your oil change interval?

Have you checked to see if the map sensor pipe has fallen off?
You popped like a virgin on Prom night. Sorry man

if your map sensor hose fell off or the sensor itself went bad, it would give exactly the sympthoms that you have right now. So you better hope that it's the sensor and not your engine, because it's a lot cheaper to replace one

The map sensor is connected, anyway to test one?

If the engine is shaking, most likely, you blew a seal.
nothing else matters, no reason to try to problem solve or any bs, the only way to determine if you have a blown engine is a compression test, stop trying to guess or listen to the people on this forum. its a very simple concept. compression test!!! now!!
get rid of the ecu, my friend blew his engine becuase it didnt give enough fuel. get a m2 or pettit, much better designed IMO.
also, dont go to the dealership, get a ride from someone to pep boys or some rice boy store, and get a compression tester, dont want to drive the car if you dont have to. in other words you dont want to hurt any other inturnal engine parts. irons,housings,etc.
now go get a tester
o ya anything below 80psi, and its gone.

zoom your engine is definetaly blown
how many miles were on it? how long had you been running it with your exact setup?
your engine is flooding while you are driving because gas is able to go in other chambers except for the combustion chamber
dont waste your time with the dealer. This is simple take out the fuel pump relay (labeled and is under rectangular black box in engine bay
then take out one of the top spark plugs and remove it from the wire. Now have someone get in the car and try to start it....youll hear the noises of the engine it normally makes 3 identical sounds...youll probably hear 1 loud sound and then 2 quieter ones in a row. Its a pattern it will happen over and over as the motor spins over....try the rear housing first thats the one that blew on both of my cars and the spark plug is easiest to get to
sorry and good luck
let me know if I can advise you in anything

If the engine is shaking like mad, the vacuum is bouncing (not constant)..... the times I've seen that, the engine is toast.

No one. You are mixing apples and oranges here.
He's an experienced FD owner. He knows what he needs to do. He's just looking for opinions about what people "think" is wrong with his car.

Come on guys, it HAPPENS - seals go.
I know everyone is conditioned to look for alterior reasons but in this case it's hands down a blown apex or oil seal. I would think a rotor bearing went or a rotor over-expanded from heat - possibly due to bad-oil flow, previous damage, etc.
How many miles on the engine?
Oil-temp gauge?
