1994 cherokee not throwing any codes other than one for my speedometer sensor .what that cause power loss? Full tune up done last week.help

 

It may sound silly but check your battery leads. I had my jeep down for 2 months chasing different dead-ends after I sank it, all because I had a faulty lead on my battery cable. Sometimes it gave power, sometimes it didn't.

 

The both new

 

Any other ideas

 

Probably a bad Throttle Body Sensor, are you experiencing bucking,jerking or sputtering?
And when do you experience the loss of power?

 

Check the fuel pressure. Check for a clogged exhaust.

 

Exhaust seems ok other than its so hot u cant getnear the tailpipe while running

 

catalytic converter glowing red when it does that? time for a new cat

 

Its not glowing red but it heats up the floor enough u dont wanna touch it...

 

What symptoms is it producing?

 

Check to see if any fault code in the ECU. Is there any backfired?

 

No codes ...justhas no power when overdrive or 3rd

 

Take it to the Chrysler/Jeep dealership!

 

What gears are you running and what size tires do you have? I think I know what the problem is.

 

33s not sure on gears..was fine until a trip to the beach halfway home no power
