So I replaced the radiator in my 92 celica GT and now I have a new problem?

Question

When I start it in the morning it's fine, but when I start it again after driving a while it shakes and dies once it's in drive or reverse if I don't step hard on the gas. It's an automatic. Also it shake when I drive it on the freeway, and at stop lights it starts to shake and eventually dies if I don't step on the gas. Is there something I could not have connected right when I put the new radiator in that would cause this because it was not a problem before?

Answer 1

I wouldn't think you could have done anything wrong, I'd say it's just a coincidence that something else has gone wrong.

Answer 2

Perhaps some sort of temp sensor?

I am thinking this because when it starts in the morning it is looking for a rich mixture, after it warms up it would want a lean mixture until throttle...perhaps if a temp sensor was unplugged it might think it was cold even after being warmed up and running too rich (any black smoke?) when you give it throttle the need for more fuel would take up the excess..

check for a temp sensor that might have been unhooked or perhaps a ground wire.

good luck.

Answer 3

sounds like you may have knocked a vacuum line off or forgot to connect one...there is a diagram under the hood that shows the vacuum line routing...look at this and see if all is in place or not broken.

Answer 4

sounds like a vacume hose did you remove one of the vacume hoses whe n working on the car before? check to see they are on tight and secure

Answer 5

Check the timing, and check the motor mounts.

Answer 6

sounds like you have one or more cylinders missing. check to make sure your coil packs didn't get disconnected and that there still firing.
