ive started to have a problem where, when im coming to a stop or sitting at a stop light my 99 laredo stalls out, it cuts right back on, but its random it doesnt happen often, maybe once or twice a day. and one time yesterday i was driving down the road doin like 50 and it did it, and then it cut right back on. any ideas whats wrong?? i feel like its something electrical, ive heard the computers are **** on these cars

 

What do you mean by "it cuts right back on"? Are you restarting the engine, or or is the engine stalling for a split second and then start running normal?

 

when it does it at the stop light i just restart the engine, but when i was driving down the road and it did it, it literally cut off and then a few seconds later started back on its on, im guessing cause it was in drive? assuming that it works the same as roll starting a manual?

 

Could be a cam sensor or crank sensor problem. Ever replace the crank sensor on this Jeep?

 

i havent, ive actually only had it for about a month now. it runs and drives fine, i even took it to the beach last weekend and it was a monster in the sand didnt have any problems at all, its just these random things its not often that it does it, another thing is when im stopped in like a drive through line or something every now and then theres a rattling sound from the trans it sounds like, and if i let off a little bit and roll forward a tiny bit it stops. which that is also random its not a regular occurring problem so i dont know how to diagnose it when its not happening other than to start removing **** or getting out in the middle of a drive threw to look at it lol

 

very popular problem, its a crank position sensor im 99.99% sure

im not sure why it cut out going down the road, that never happend to me

 

The rattling you describe could be the catalytic converter, is the sound a dull tinging that changes with RPM?

 

yeah it is, i could have busted it drivin on the beach it was a pretty rough (but fun lol) ride from all the jacked up trucks makin the ruts deep as hell. and ill try the crank sensor, preciate the help guys

 

Its the computer. i had the same problem and tried replacing both cam and crank position sensors till i argued with my dad to either sell it or get a new computer thankfully he got the computer for it instead.

 

Because the ECM fixed your problem does not mean it will fix everybodyy's problem.
This is a tip for everybody: If you're not sure what is wrong and not sure of how to properly diagnose what is wrong, have a shop do all of the diagnostic work for you. That will save you money and a lot of headaches. Throwing good parts after bad and using the "WAG" (wild a$$ guess) method of repair is just wasteful.

 

i had that problem to, new cat fixed her right up, sounds like a hot rod now

 

well i dont really know whats going on, it hasnt done it in the past couple days its actually been runnin great so i dont really know??
