Does a 1997 Jeep have a carburetor?

Why does my Jeep Wrangler not start on its own?
But she’ll crank and crank but won’t start unless I have the throttle wide open. Once she starts, she won’t idle on her own..I have to keep my foot on the gas. But this doesn’t happen every time, only when cold.
What to do if your Jeep Won’t Keep Running?
If it still acts the same hold the gas pedal to the floor, once it starts then start to back the gas pedal off until it will finally keep running on its own. Dave Ask Your Own Jeep Question
Why does my Jeep Wrangler idle all the time?
One more part that can cause a bad idle is the Throttle Position Sensor. My TPS went bad and my idle and acceleration became unbelievably erratic. Try cycling the TPS via the throttle linkage 40-50 times (without the engine running) to see if anything changes.
Why does my Jeep stall when I start the engine?
If it starts, the fuel pump is the problem. If not, the engine should be checked for spark. It could be a sensor or computer-related problem. To be absolutely sure, raise and support the back of the Jeep on jack stands, unless the height allows you to crawl under the back without raising it.
