I will try to keep this brief. I would appreciate any help/suggestions on my problem.
I recently purchased a 2001 Echo (standard tranny) with 130K (80,000Miles). The car performed fine for the first week.
Yesterday on the way home from work the check engine light came on. The car was driving perfectly.
I decided to clear the error, just in case it was due to a simple error and if the engine light came on again, I would be certain of a problem.
The car drove perfectly to work (100K) this morning.
Leaving work today, I backed out of the parking spot and the parking brake light stayed on, flashed, stayed on even though the parking brake was off. ALso, the car idled very rough - close to stalling and even with the clutch engaged, there was a noise almost like the clutch wasnt engaged. The noise almost sounded like you were trying to start the car, even though it was running - only when the clutch was engaged. I needed to reve the engine to avoid stalling, and the parking brake light either flashed or stayed on until I got up to 80KPH (50MPH). I drove this speed to avoid any damage to the motor. After about 5 mins at a constant speed, the parking brake light went off. I drove for about 30 mins, and when I took the offramp the car again drove very rough and the brake light came on again - flashed, or stayed on constantly.
I have searched to try and find an answer to why this has happened but came up short.
Any help would be very very appreciated. |
It sounds like you have 2 problems.
#1 Brake light on at times, usually means the fluid is LOW.
This is either from a leak, or the brakes are near 50% or less.
Have the brake system checked for leaks and pad %.
#2 sounds like an engine miss. Have the codes read next time the engine light comes on, this will help us in the right direction. FLASHING ENGINE LIGHTS mean that whatever cylinder is missing has over a 50% failure and will cause engine and catalyic converter damage if not fixed ASAP.
Cleaning the MAF will never hurt, just go easy and use electronic parts cleaner and air dry, NO COMPRESSED AIR.
I would also advise a TUNE, use NGK or Denso plugs, NO CHAMPION/BOSCH/AUTOLITE/DELCO.
Then roadtest. If this miss is gone. HOOORRAHHHH
If the miss is still there, then mark the coils with a MARKER, then swap them in different cylinders and see if the miss moves to a different cylinder. You will know this by reading a NEW code.
If it moves then you have a bad coil, if it doesnt (bigger issues).
I would start here, ECHO have been very reliable and problem free for the most part.
Let us know what you find.
