Hi everyone my ECU took a dump on me and I'm trying to find a new one, I have a 95 GT Manual. I wanted to know if an Auto ECU will work if its a manual or do I need to find the manual one?

so help me out some more here. Are these symptoms of the ECU Failing, Hard starting where you need to press on the gas to get it fired up. when its running if you let go of the gas it will shut off and the rpm needle will spike up throwing codes. It will smoke out the exhaust when it starts up from burning unburnt fuel.
I have changed the distributor because it was failing and had oil inside of it. I got a new distributor, cap, and rotor. |

It will smoke out the exhaust when it starts up from burning unburnt fuel. I have changed the distributor because it was failing and had oil inside of it. I got a new distributor, cap, and rotor. in my experience failing ECU's don't all act the same way. In the 3 cars that I've worked on that have had bad ECU's the symptoms are below. The ECU throwing codes and spiking the RPM gauge with the car off does seem like a faulty ECU. The celicas get the RPM signal directly from the ECU I believe, so it makes sense to see the RPM gauge jumping if it is bad. You should check your grounds on the car, more specifically the ECU ground that I believe is under the center console. The ECU had to fail for a reason, and I know it's not a common problem for the celicas to have ECU failure. Bad grounds will generally cause electronic components to fail. Some cars have faulty capacitors in the ECU that fail over time, and they leak on the circuitboard problems (problem that I thought I had in a turbo eclipse that I had, common eclipse problem). Car 1: (OBDI early 90's Honda) ran rough all the time, smoked, and sputtered. There was a light on the ECU that blinked certain codes to show the engine code. It was solid, and didn't blink. Car 2: (OBDII late 90's Volvo) wouldn't start at all. Car 3: (OBDII early 00's Nissan) ran rough, smoked, sputtered, could not read ECU with diagnostic scanner. -------------------- -Jay
