Okay guys.i have a Local 2004 Mitsubishi lancer CS3.
The car has a standard 4g18 engine with a standard CVT Tranny.
My cars lacks power.Extreme loss of power.
I feel the power there but its like something is holding the car back.
When climbing inclines the cars runs out of power and sometimes won't make it up depending on the incline.And thats with a wide open throttle(pedal to the metal)
In reverse the cars barely moves.
Also if i cold start and i drive it i get this sorta jig saw back and forth feeling from the car until it warms up a bit.
The engine sounds noticably heaver when idling also.
Over the past 4 months i've been trying to tackle this issue but still the problems exists.
First off.There's no check engine light on.The car drives fine when say i'm doing 60 to 80 on the speedo but say if i decide to press for acceleration the car revs out and goes nowhere.The speed barely increases.The engine would rev but no acceleration.
Things i have tried over the past 4 months to diagnose problem include:
Take car the for engine error code scan.
Change transmission oil
Change engine oil
Change air filter
Change plugs
Change valve cover seal rubbers and gaskets.
Clean injectors
Clean throttle body
Change CAM sensor
Change Crank sensor
Change MAF sensor
Clean IAC sensor
Clean TPS sensor
Clean fuel pump filter
Check fuel pressure
Test MAF,IAC,TPS,O2 sensors manually with voltmeter
Manually inspect exhaust for clogg
Remove catalyc converter
Check engine timing.

Everything that was checked or changed or tested is and works within their intended range.No fault codes or faulty sensors.
Yesterday i spoke to a transmission repair man.He mentioned to me that it is infact my transmission valve body :shock:
Something about to my gear1 to gear 2 shifting solenoid is gone :(
Could this really be my problem???
Anyone here ever been through or know someone with similar problems????
I'm desperate been kinda wasting lots n lots of cash and time behind issue.
Can a transmission valve body cause these symptoms??????

Inside..... i have a similar issue not as bad though. Sometimes when i'm driving between 100-120 i feel as if my car is holding back for a second or two then it continues to accelerate or drive normal. It's not over reving or anything like that it's just holding back at times. I recently changed transmission though because my previous transmission stopped working. The gears are going in without any delays or anything like that. Don't know what's causing it and it's annoying.

Groundcontrol first off you should really ask your question in the CS forum. Mostly all CS problems are covered there.
The CS forum had this issue early this year. Brotherhood, missyniques1 and some one else had this problem or similar and yes the solenoid could be your culprit.
Get advise from jentons ( transmission specialist in the east). Jentons is tested and approved by alot of CS owners so the last call is yours.

Also it would help if you put up the OBDII code/s

pm Brotherhood for more details about transmission.
