Hesitation and stumble
 

Hey guys. So i recently broke down and after fixing the problem, something else has arisen. The cam sensor and synchronizer both went at once about a week ago. I replaced both myself and after, the jeep started right up. But after letting it warm up, i went to drive it and as soon as i hit the peddle, it feels like it is gonna die. it stumbles for a split second. Its so quick the tachometer doesnt drop, but you can definitely feel it. But then it goes back to normal and roars to life no problem. I find it only happens once it is warmed up. Before it hits 210 its completely fine. The only thing i could think of is the synchronizer needs to be reindexed. Any help is greatly appreciated.

What year and engine? Have you checked it for codes?

What was the original problem before replacing the cam position sensor? What brand did you get? What do you mean by the synchronizer? The sensor replacement takes just removing the two screws without disturbing the position of the "synchronizer ".

Sorry. Its a 2000 4.0. And the sensor was a dorman. I replaced the sensor but the thing that it sits on. The synchronizer. Was bad too. It ate up the original sensor. So I had to get the whole thing

It sounds like you got a bad cam sensor or your crank sensor is on it's way out. As for the sensor you want to get only OEM sensor. The aftermarket rarely work and are often bad right out of the box.

damn, so looks like ill buy a new sensor.. Should the synchronizer be okay because that is dorman too. It looked pretty well built tho

Underneath all that junk is the distributor dive gear nice and tight still or sloppy?

Don't forget crappy wiring will cause all kinds of headaches.

Everything you mentioned looks good

Okay so i finally got the mopar cam sensor and while it helped a little bit. It still stumbles when giving it gas. Sounds like its starving. Im at a loss now so any help would be great

Also, just noticed that on a cold start up, it will run pretty rough for like 20 seconds then go back to normal. Dont know if that is related or not to the cam sensor

Have you checked it for codes yet? You can also make sure that you have the right fuel pressure. Your 00 should have 49psi +or- 5psi at the fuel rail.

i can check it tomorrow for codes but no check engine light and ill check the fuel pressure this weekend

Sometimes you can have stored code without a cel.

no codes stored. And i tested the fuel pressure. Got 45 psi steady. just replaced the CPS today and while it helped with smoothing out idle it didnt fix the stumbling problem I got a video of it so ill upload that later.

heres a video of it stumbling. right after the video ends we stalled it out just by revving it.
