Question about Saturn SL2
I have had the ECM or (ECU) replaced because that is what the code originally said the problem was. Well to replace it cost be over $500 and I am still having problems. I have been back to my mechanic twice, the first time the car wouldn't start so he had to replace the new ECM with the old one to get the car to the garage. In order to disconnect this he needed to disconnect the battery and hence lost the code he said. He then put the new one back in and had the car for several days driving it with now problems. When I got it back home it sat for a few days, I used it once with no problems, then the second time, when shifting into 3rd gear the car hesitated when I gave it gas, then there was no throttle response at first then very slow. I got it to work, and a few hours later it got me home without any problems. Then my son drove it and had the same throttle repsonse problem and he said it seemed to be missing on a cylinder. My mechanic says these problems are not uncommon with OEM ECMs, but I cannot drive the car like this, any ideas?

As the old ECU worked I doubt it was faulty.
Get an auto electrician to check the wiring.
An ECU will not give a code for its own fault!

One question, have you replaced the ECTS (Electronic Cooling Temperature Sensor)? These cause no end of different seemingly unrelated problems on Saturns. Peice is about ten bucks and is an easy install. Just search on youtube for a how-to video. Even if that's not the problem it is reccommended to replace this peice just the same as they ALL end up going bad at some point.
If that's not a fix, start pulling plugs. Check to see if they're correctly gapped and if they have any damage/corrosion. If you're running Platinum plugs, immediatly change to a copper plug as Platinums have no place in these motors. Most people have the best luck with NGK copper.
Check to make sure that your plug wires haven't been crossed. This sounds like a plug or wire issue most likely so it has to be in that family, if the plugs are good, wires good and not crossed, sensors are fine, then time to replace your coil packs. If you've replaced everything up to the coil packs then that is most likely the cause of your dillema.

the battery says 12 volts but may be dropping to 4 or 5 under a load...i would suggest jumpstarting the car and see what happens.the battery should read in the high 12 volts and not less than 9.5 under cranking. the dash lights go out on your car when starting,and the alarm will go off ,and disable the ignition if the voltage is too low in cranking the car because the computer will shut it down and activate the anti theft.....check your battery posts are tight. best of luck

You the beginnings of what is known as the reverse slam. If caught early enough it is fixable. However, most times a rebuilt valve body is in order. I do it for around $200. For the record any late 1992-2002 valve body will work, those are the type II. Type I won't work and is 1992-early 1992 years.
