anyone knows why this happens? Help PLEASE

[mephist0]

Ok, first to start I purchased my car a few months ago and it has been running poorly, (the problem with the car is that it wants to die, which never does when it is hot and the tachometter dont work it goes up and down and when I step on the gas it goes to like 2000 RPMs and it goes all the way down to ZERO and it stays there till the rpms go down)By now I have been fixed some things on it I fixed the O-rings on the throtle body and checked for boost leaks and it leaks no more, I also replaced the Resistor pack and Coil pack, and the car is still doing the same damn thing, any experts on this stuff>????? thanks in advance

I did alot of things to the car already, and haven't found the problem

Update: Thanks for all the help guys I swapped the ECU and now the car works/runs like a dream, THANKS

Although I found my studder problem, if only my tach would stop with the mexican hat dance

 

[mephist0]

have you replaced the Noise Filter Sensor??? or cheked it?

 

[pianoman]

No not yet, when I datalogged my car the other day so I could check a couple of things on top of my tach, it decided not to play hopscotch.

 

[mephist0]

good luck man, wish you the best with your car, I'm so damn happy, 3 months trying to find this problem and now it's fixed >=)

 

[pianoman]

did you have leaky caps?

 

[mephist0]

nope, no leaky caps, I don't really know what was wrong with the damn ECU, but it looked like someone replaced them but they only replaced two of them instead of the three. maybe your ecu is bad??? who knows, did you know that you need to disconnect your battery before you remove/replace your ECU?

His ECU works fine in my car. It sould still be a problem but I'm betting more on 15 y.o wiring and noise filter.
