96 jeep cherokee timing chain failure part 1 

New sub! Bro my 07 jgc laredo w 226k I just replaced the throttle body cause tb light flashes recently n felt the surge n rpm jumping so I amazon the new tb for only $70 lol but now I get p0507 but everything runs perfect no leaks no nothing I wonder if she just don’t like aftermarket and it’s lighting up because it’s not oem 🤔

Your compression stroke will have the marks both at 12 o’clock. The rotor button will be pointed to number six cylinder when the marks are pointed at each other.

Same thing happened with my 1994 XJ Sport

That timing gun only flashing when engine running

How many miles were on it when it jumped time?

I bet it was not the timing chain.

Is this a 4.0
