Self diagnostic test codes

Nothing. Once you put the Turbo on you will detonate the engine.

Sounds like serious internal engine issues...

Your problem is most likely because you are describing your vehicle as a "Gs". The only similar listings in the catalog are for a "GSX". (The parts counter person probably has no clue that there is a difference) The GSX is only built in a turbo version, therefore you will not find a water outlet for the non-turbo version...it simply does not exist.

Now, if you simply describe it as an Eclipse, there are water outlets listed for the turbo 2.0L, the non-turbo 2.0L and the non-turbo 2.4L engines. You did not bother to mention engine size, so I will list the part numbers for BOTH of the non-turbo engines.

For the 2.4L engine: Compressor Works Part Number 815517

For the 2.0L engine: Compressor Works Part Number 815576

Both are available from AutoZone

did you forget about the piston rings or the bearings

You have an electrical short to ground on that circuit , do you know how to test automotive electrical circuits using a DVOM - digital volt ohm meter ? How to read a wiring diagram , so you know which circuits to test ?
What fuse ? number an amp

The fuel pump relay for the 2.0 non turbo is mounted on a bracket at the
left rear of the engine compartment. On the 2.0&2.4 turbo it's located
behind the center of the dash. Hope this helps.

P1494 code can cause by EGR lift sensor.

When the engine is cold,disconnect the EGR sensor connector and clean the contacts.

Reconnect the EGR connector and reset code.

================

If the code does come back then I will clean the carbon under the EGR valve (or replace it)/
the EGR air passage MUST be clean also.

Please order a EGR base gasket before you start this job.

It's very time consuming but it preventive you must do.

This should free up the movement on the EGR.


I will ran a FULL TANK of Chevron gas to clean out the injector also.


Reset the code and you should be fine.


Please post more information on the comment window.

It is built into the air cleaner lid.

That's wrong and the mechanic should know that. For 96 and newer cars, OBD 2 (onboard diagnostics, second generation) systems are in use, and the codes that come up are four digit codes.

That means that the code you got is 1255, not four individual one-digit codes (even a pre-96 car would have two digit codes, not single digit). Generically, a 1200-series code deals with fuel and air metering, but unfortunately I don't have a listing for a 1255. What symptoms does your car have? Is it just bad gas mileage or is it acting up in other ways? Post up as a reply here with anything along those lines that you can think of and I'm sure we'll figure out the problem.
