gen 7 Throttle valve cable

Hey guys I have a 1993 Toyota Corolla Dx Station Wagon 1.8L 7AF-E with a A245E transmission.

My Question:
"What would happen if the the throttle valve cable were not in the proper adjustment?"

Because my wagon is having problems with acceleration I think... it seems to be heavy when driving and lazy. There aren't any problems with the trans because it is taking all the gears... so let's see if you can help? Thanks in advance!!!

if it were too slacked then it would not downshift into lower gear like it should when the accelerator is applied. take some slack out and see how it does, car needs to be totally warmed up when making these adjustments.

I messed with the throttle cable on my old 94 corolla once when I thought it was behaving the same way. It did help, however be very careful, as slightly too much of an adjustment can make you idle at 30+ MPH.

A loose throttle cable with result in poor throttle responce, it's very easy to adjust with the two adjuster nuts. If the trans kickdown cable has slack then you might encounter shifting issues, it's not a very common issue.

If your car seems to be having trouble moving, try doing a Fuel System Tuneup with Throttle Body Service. Add fuel injector cleaner to your fuel tank and then clean the carbon build up from your throttle body and plate. This should help out quite a bit. If you are still having issues; check your spark plugs, distributor cap and rotor. If worn; replace! One last thing, if you have an adjustable distributor, make sure your timing is set correctly with a timing light.
