The part I do not get is how are you loosing temps on one side of the motor? I thought I read where 2 would drop then 4 etc.???

Pantera, Sorry to here about your problems.
Does the temp drop on the cylinder and then the ignition starts to drop out, or does this happen at the same time. If the ignition is dropping out, I would think the temp. would then drop because of no fire. Somehow you need to determine if the ecu is causing the problem or something else is wrong causing the ecu to shut it down. Sorry i'm not much help.

Battery voltage is 14V, before during and after the cylinders drop out.

Plugs have been checked 4-5 times after this has occurred and look normal, light brown on the insulator down in the plug. Does not appear to be a lean or rich condition. I'm looking into the water issue tomorrow - going to pressurize the system to 15 psi and check for leakage or leak down.

Valve springs have been replaced and upgraded to avoid a problem with valve float or the boost issue. Unless they were incorrectly rated this should not be an issue, but I will bring it up at the dyno session tomorrow.

If you run the engine from idle to 3000 or 4000 RPM and hold it under a load, after 20+ seconds the engine missed and then the EGTs on the # 2, 4, 6 and 8 cylinders go cold. However the other night, we ran it up from idle to 5,500 RPM under load and it appeared that the # 1, 3 5, and 7 cylinders went cold.

I have tried a new ECM, no change, it does not appear the the ignition drops out, as we have a timing light hooked to #2 and it continues flashing throughout the situation.

Thanks for the input, I will and do check everything that people recommend and will post the results here. You know there are going to others with this situation and it will help them also!!

Thanks Again,

Kirk

Kirk, one easy thing to look at would be to mark the crank for #2 cylinder and hold the timing light on the mark and see if the timing is doing something wierd when it starts to mess up. Something has to be causing this.
Just throwing ideas in the air.

The ECM is a MEFI3

I'll try the timing mark idea today.

Thanks

MEFI3 should be 1999 and up

I have not read the first thread but could it be the coil is overloading or geting hot & thus reducing the voltate to the plugs. The timming light will still fire but when motor is under load, plugs need more voltage to fire. What gap are you using on plugs & what kind of plugs? Have you tried changing the plugs

Good Idea Turbo, It's something easy to change and I have had coils go bad and they do some really wierd sh$t.

Thanks Turbo, I will try the plugs today. I did run another set in the begining and I'm sure there was the same result, but its cheap and easy to try. I'll see if I can dig up a coil also.

I'll be trying the items listed here later today.

Thanks Again,

Kirk

What injectors are you running? Are they the same impedence as the original? Could the ECM injector drivers be overloading?
