cant figure it out ...bad ecu?

igopoopy · Feb 20, 2005

my car will run great till it has been at operating temp for about 20 min.
then it will start to studder (then i floor it nothing happens) then it will go to 0 rpm
and die.
if i let it cool it will work normaly :confused:

i did a compression test and they where all good

fule is good
air is good
when it runns like shit i dont get spark :confused:

plz help this is my only car and i missed 3 days of school already

a few things to check if your not getting good spark would be your Cas, power transistor, coil pack or ecu, but the whole runnin ok cold then bad warmed up, i would think more Coolant temp sensor, but thats fuel related...make sure your ecu doesnt have leaky caps :thumb:

hope that helped

i put a new Coolant temp sensor caus the old one was messed up.
Cas is fine i did change the timeing a little tho runs better.
ecu is the only thing i can think of how hard is it to take it out?(dont whant to get in too deep)

It's not hard. The basic steps are shown at http://www.technomotive.com/howto/ecu1g/checkeprom.htm

would a ecu out of a 90 n/t 2.0 work in my car 91 n/t 2.0

Close to the same issues as the turbo cars, using the '90 ECU will require you to swap pins 6 and 14 but since your NA and don't have the MAF reset wire you only wind up moving pin 14 to pin 6 so that the IPS wire is on the right pin.

I see 91+ NA ECU's on eBay all the time and I think Maviski has one he wants to get rid of.

If you have a very small jewlers screwdriver to release the pin it takes about 30 seconds.
