In order to remove the exhaust, you had to remove the intake as well. Chances are that you have a large vacuum leak either from a wire getting caught between the manifold and the head, or just forgetting a vacuum hose connection somewhere. I can't see what you did from here but that's the two places I'd look first.

My 03 wrangler will not rev past 3,500 rpm


Do you have a trouble code for the throttle position sensor ?
If you have normal fuel pressure, the TPS would be the next thing to check. Problem could be in the harness between the sensor and the computer too.

94 wrangler dies in gear


You don't need a scanner. If you cycle the key off and on 5 times, the codes will start flashing. Here is a link to jeeps and their trouble codes. There aren't that many in the older OBD-1 systems.

If you have no trouble codes, check fuel pressure. Multiport injection is high pressure, above 40psi, but Jeep would have specs.

1993 Jeep Wrangler, all of a sudden when started first thing high rev. then drops and dies without foot on the accelerator, Manual trans. What could this be.....


I suspect your Idle air control motor - typically mounted on the throttle body fuel injection models. This is not something you would typically have the right scanner to test, but your local shop should be able to test it quickly - meaning it is not an involved exam to see if it's bad. However, it IS an easy fix and if you have basic mechanical skills you should be able to change it yourself. You should be able to keep the engine running if you keep your foot on the gas lightly at all stops, but be careful not to push too hard on the gas - the engine is stronger than the brakes!! I would suggest having it towed to the shop unless your mechanic makes house calls!!

06 Jeep Wrangler making a loud clincking or grinding when turning


Hi there,

By any chance is the transfer case engaged?

A locked drive train could account for the noise being made only on turns.

Bring the transfer case to neutral then back to 2-high.

Or try to duplicate the problem by putting it into 4-high. THAT way the dealership would know exactly what to look at.

95 wrangler yj. has no power at high speeds


Have you had fuel pressure tested, and/or filter changed. Have you checked for plugged exhaust, such as catalytic converter? Quite often engine will also run a little hotter than normal when exhaust is plugged.

Describe your 1997 Jeep Wrangler 1997 jeep wrangler 4 cyl idle fluctuates 900 rpm to 400 rpm after warmup no service engine light but check guages light comes on momentarily when rpm gets low and oil press...


The check gauges light is normal because at 400 rpm it isn't running fast enough to build sufficient oil pressure. I am guessing maybe a vaccum leak???

97 Jeep grand cherokee 6 cyl. idles down to 0 and dies.


any leaks in intake or exhaust upstream of the sensors, sparkplug condition and engine controls/sensors for out of range operation (including fuel pressure and condition of regulator)
IAC should be cleaned and checked as this can cause poor idle and shut down. I'm not saying not to change O2 sensors, but unless everything else if OK, it probably won't help.

2000 jeep grand V8 low idle then dies


A faulty gas cap can cause the sensor to come on.
Clean out the throttle body with a cleaner and see if the idle improves.
