There is some loose connection between the delta connection side of the engine and the spark plug so check the connection and then there wont be any starting problem

My 1997 non turbo toyota starlet cuts out sometimes when driving. now it will not start. any help would be great?


Do you have a check engine light on? If you do, go pull the codes and post them. That's always the first place to start. Anything until then is just a guess. Crank sensor, cam sensor, fuel pump, vacuum leak, so many possibilities. Let me know if you get the codes.

Toyota soarer twin turbo 1991 model running rough any ideas as to what may be causing my car to play up like this?


Hi Chris:
I'd start with standard maintenance procedures:
- Air Filter
- Spark plugs
- Fuel delivery system clean.

Depending on milage and maintenance history, a 1991 engine will be starting to display signs of age. Valves, timing linkages, rings, etc. age creeps up on them. "Rough" is usually associated with mis-firing. That leads it spark and fuel as the primary check, and then compression as the secondary diagnostic that I would be looking at.

Hope this helps.

I have a 93 Toyota soarer it starts and runs till you rev it then it cuts out


you may have an electrical problem or a vacuum leak somewere,it can also be a problem in your fuel system so check your battery connections,then your fuel pressure then while its running get some carb/spray and spray around the intake and throttle body and listen for any change in the engine and if or where you hear a change thats where some of your problem is

Can a subaru engine fit in a toyota estima? has anybody tried it and got successful? i want to change my 2.2 turbo diesel engine to a 2 litre twin turbo subaru engine


No. engine mounts, electrics, ecu, axels and a whole lot of other stuff would need to be changed and cut and welded.even after that you could have a host of other difficulties. not an easy task for even the experienced engineer.

Turbo dash light comes on when ignition is on when starting truck. when driving and turbo should kick in no light comes on. Does this mean turbo is broken?


you think? its probably telling you that at least something is not working appropriately..while driving have a buddy climb out on the hood, no, take hood off so he can really see, punch it and tell him to
see if the turbo comes on. easier when starting, if the light comes on,
look at the tach, if its screaming 7K then it might be on, else, its probably broken.

Has he checked the turbo, pressure? How is your air filter? could be a short to the coil for the pump Try running a couple of tanks of amsol additives cleaner, may just be carbon deposits forming on your injectors.
