Is it amber coloured? If it is have Auto Zone, Kragen or any chain parts store run a emission system trouble code test, then post the code back on this thread, let me know.

Actually, just go to your local auto parts store and check the codes for free. If you go to a dealer, look forward to shelling out a minimum of $75 dollars. Most of the time its a oxygen sensor or something like that.

P0505 means the whole Idle Control system, not only the IAM. Check all related sensors (i.e. crankshaft sensor). Check with a voltmeter direct at the connector of the IAM if you get any signal. Remove the IAM from the TB, connect him, let someone switch your ignition key to ON. The IAM need to drive in/out for a short time to find the right position. Hold the IAM near a hard part, that they cant drive out completely! If IAM works fine, check the fuel pressure, check and clean your TB ( if not done yet). If that doesn't work, come back again please

check all the fuses before you do anything else. After all a fuse provides power to the electronic box that controls the transmission. Other than that I would not advice on a more complicated troubleshooting since there is no way for you to test a bad transmission computer, even mechanic shops don't know how to test them. The only thing they would do is slap a known good one and see what happens.

Rear light and brakelight don't work when headlights are turned on 1999 Jeep Grand Cherokee


My first guess would be a ground problem.
The headlights and tail lights are controlled by the same headlight switch, but the brake lights are on a totally different circuit.
You may have to get a shop manual to get the wiring diagrams needed to troubleshoot the circuits if the ground connections are ok.
The lights involve the body computer and other components.

The miss,does not just come and go,if it is a engine valve,replace the coil and boot,go from there,if this does not solve the problem,then the injector is gone out,or going out.If it is a engine valve,the miss would never get better,then worse,it would be the same all the time,get him to run a air compression test,get the valves up(close)and see if any air is detected threw the exhaust,or the intake,it will be present if the valve is the problem.

Get the check engine light checked you need to figure out the codes. Could be low on tranny fluid. If rpms go up and only moves for a short distance at 15 mph. Could be tranny fluid.
