Major Engine Problems Rendering My Car Useless

car: 1995 Legacy L. JDM EJ25DE, AWD4EAT

 

storyline:

 

1. start car - it takes a noticeably few extra cranks than it should from sitting a couple days in the snow

2. car idles while i brush snow from windows - from a start, it's fine.. it revvs waaay up for 3-5 seconds then goes back to normal

3. warm body in seat - notice a small amount of smoke coming from engine, i thought of it as nothing more than the current exhaust leak from my header

4. start to reverse - bald tires i give it a considerable amount of gas to overcome the mound of snow behind me, engine revs higher but car slllooowly increases speed.

5. 'Drive' - mobbing throught the snow i didnt notice anything wrong, i finally made it onto a clear main road at a light

6. From the light: i give it about 90% throttle and the car starts revving up and down as i accelerate like a turtle, the tach is slowly increasing though as normal - when the tach shows around 3-4krpms, something happens and i take off with heavy acceleration.. i was unaware i had vtec

 

thats been happening alot lately.

 

today after #7 i was at a red light after i'd driven a total of maybe 1 mile, and something happened that sounded like a backfire and my car slowly sputtered to its death, it started, ran, and idles forward albeit slowly but surely without problem but as soon as i hit the gas AT ALL it dies.. had to push it home in the snow.. seeing smoke from the engine.. it wasnt white or thick just exhaust type... and smelling metal type odor faintly as well

 

prior to this i ran a few weeks without a cone or any other filter attached to my maf sensor, it is on now.

 

i have a CEL from the engine swap (PO106) - havent yet checked if there were any others

 

 

im out of a car right now so info wanted!

 

thanks

doubt this is major engine problems. major annoyance for sure! you need to get the codes from the check engine light.

guessing won't help much. read the codes and let us know what they are.

 

plugs and wires are likely - how old and what brand are they and is it worse in wet/humid weather?

or the coil is hosed.

the plugs, wires and coil came with the motor from tigerjapanese.com in nov/dec of 2008.. so those all no doubt need replacing

 

i had always had that code though since the sawp, i thought it was due to not tapping the EGR into the motor when i swapped it... its run fine with it on until recently so im not sure if thats it

 

some more info..

tonight when i turned it on, despite it taking 100000 turns to finally start, it idles for about 5 seconds then dies, upon turning it on, the 'AT Oil Temp' light blinks 16 times..

 

i noticed unusual smoking.. upon inspecting, it appeared to be coming from the front part of the motor as opposed to the heads..although still not overly thick or white.. also after the car died it looked like it may have been coming from under the car as well, near the trans or cat

i'm also running on the stock ecu from the 2.2L and tired unplugging the MAF to see how it ran in limp mode but it will not stay idling for more than a few seconds now

 

also right as it started sputtering before it died tonight, a 'pop' sounded like it came out of the cone filter.. i thought that was odd

Is the starter motor BURNING up? Starter motors are very powerfull and draw a ton of amps. They're designed to be used for a few seconds ONLY.

Yep, 100000 turns will pretty well burn up a starter motor.

we're trying to help, but you're wasting your time at this point. have you read the check engine light since this problem started? so far you've indicated you have not. it might be telling you exactly what the problem is. it's silly to guess.....fuel pressure, vacuum leak, crank sensor, cam sensor, igniter is hosed, coil pack is hosed, plugs, wires, TPS, ECU issue......too many possibilties to just start guessing and trying things.

 

if you're fired up to guess and try things, the place every mechanic would start would be to check for spark at each plug while cranking.

then pull the fuel filter hose and see if fuel squirts out (i prefer that method over a gauge, much quicker and no equipment required).

 

if that pre-existing code didn't cause problems before, it's not the issue now, you would be interested in new codes.

the non-EGR thing won't matter either.

definitely right on and it will kill batteries quickly too.

The tranny has it's own comtrol module and the light you are getting is most likely the duty c solenoid gone bad, but you need to pull the tranny codes to be sure. You will need to search for tpulling tranny codes to get the procedure. You cannot get them with a scan tool. If you need an MAF let me know, I have one sitting in my shed.

pinpointed to MAF problem.. however... is that whats causing the TCU to throw a AT Oil Temp code? or do i have an additional, separate issue

 

when i did my most recent ej22 swap, i started my car with the maf unplugged. i was trying to isolate a different problem. but the car started and died, threw CEL and started the AT Temp light flashing. once i reconnected the maf everything went back to normal.

 

the tps can also cause a TCU code and flashing. several things will.
