Low revs and sounds like a WRX

[vicko]

Ok so I did some researched and thought I did everything, but my car isn't working and I need some help. Recently my car started going slow on the highway and it seriously took 5 minutes to get to 60mph. God forbid I had to slow down unless I was in the far right lane, because it was a PITA to get back to normal speeds. Anyway, I cleaned my air filter, changed spark plugs, cleaned AND replaced my MAF, sprayed carb cleaner in my IACV, nothing's helping. Any other suggestions?

Also, please don't shoot me, I searched and I've been on this site since I got my 240 in 2004. Please help :naw:

If it sounds like a wrx you are down on a cyc or two. Maybe electrical spark on them.

[5t341tH]

test ur injectors, or spark plugs.
pull each spark plug out while its running and see if the note of the engine changes. if it doesnt, that plug is the culprit

[Z33dori]

coil packs/spark plug wires
or your injectors

your running on less than 4 cyl

yep, i already had this problem, mine ended up being coil, then injectors. and i recomend getting lucas injector cleaner,

[HS13KLS]

check your rotor on your distributor.
mine was ate up. replace it and your cap. i bet that helps/fixes the problem
and like drifterdave said

check your coil, that was my problem before also

When I was running on 3 cylinders (no 2 went out) it was just a dirty injector. I would buy new o rings, and pull them all and clean them. In addition clean your spark plugs, then re fire the car. If that doesn't work then look to the wires. If it's just an injector change your fuel filter asap.

funny thing i just talked to my friend and i told him i wanted my car to sounds like a wrx, and he said make it run on 1 cylinder or 2 it will sound just like it!
so there is your answer, you have dead cylinders,

start it and start pulling the spark plug wires to see what ones they are, if it sounds like it made a difference when you pull it then its a live if it doesnt sound like it made a difference then you have a dead cylinder, GOOD LUCK=]

Mine sounded like a WRX when I blew a piston ring.

[vicko]

you think maybe having a cracked exhaust manifold and missing a bolt would do that? LOL

injectors are fine
plugs/wires/distro/cap/rotor fine

so yeah I'm gonna try the exhaust mani first

[gotspins13]

??????????????have you checked if you have dead cylinders yet?????????????????

[FaLKoN240]

You guys know he doesn't have to take out the sparkplug wires.

He should just unplug the injector clip.

You might have a dried up/dead o ring on your injectors.

1. Start your car

2. Get it to idle

3. Have a friend watch the RPM gauge

4. Unplug one injector clip, does the RPM change? Did the engine stumble?

-If it did, check the o-ring/replace the injector.

-If not go back to step 4 but try a different injector obviously.

[vicko]

Sorry for the omission, yes I did check the spark plugs and cylinders and they all make the engine stumble, thus ruling out any bad injectors/plugs.

I am sure the huge crack and missing bolt from my exhaust manifold may have something to do with it, but please keep offering suggestions!

[goldee240]

timing? smoke? go run a compression test see whats up probably a dead ring

[jrodasjr]

same problem but guessing its spark plugs

[stealthgti]

Sparkplugs, did you get the right heat range?

Wow, just read your response to the crack and the missing bolt. Way to go on not supplying key information.

:naw:

[FaLKoN240]

Yeah an exhaust leak can fuck up your shit.

I remember I didn't have my EGR hooked up all the way and the car ran like TRASH.

GET THAT FIXED.

Im having the same problem, i just installed my buddy club spec 2 exhaust on my s14(1995) with ka24de(going sr20det in a few months) and today i washed the car and the engine(pressure washer) and it ran fine i left it running while i washed the motor, but i went to a friends house and the car drove there fine, but when i started it sound like it was running on 3 cylinders(wrx sound) along with it bogging down, and just feeling powerless for a few seconds, any ideas what could cause this, im gonna pull the plugs and check the wires tomorrow morning just wondering what you guys think :)

Maybe water got in something it shouldn't have? would adding that exhaust have anything to do with making the motor act like this?

I'm sorry...I didn't see it posted, but is your car Auto or Stick?? Also, did you put your car in Diagnostic Mode to check to see if your ECU was kicking out any codes?? That would help alot as you didn't mention it in your post. Check for DTC's and get back to us...

[vicko]

stick and yes I checked codes and it threw the MAF code, haven't checked since I replaced it.

right now i'm concerned about the cracked mani and i'm trying to get one at the moment

[vicko]

sorry to bump but I figured it out and it was the catalytic
it looked like a coral reef inside, that's how melted the ceramic was

knocked it out and it ran like a champ
