Most modern engines should increase RPM's when the load on the electrical system increases, as the Engine Management system should monitor voltage and identify it being drawn low, so increasing RPM to increase output from the alternator. Even many older engines would do this.

If you have done any performance mods they may be contributing to your cold idle problem. Exhaust or air intake mods may put you in a borderline lean condition. You could have a lean idle circuit. This could be an adjustment/calibration problem or a dirty carb. When you open the throttle you bypass the idle circuit and the accelerator pump richens the ...

I would suspect that this is the problem: I have absolutely no idea what can be causing this. I recently cleaned the carb and rebuilt it with all new needles and everything. Any help is greatly appreciated. Rebuilding your carb is a tricky thing that if you don't get right could lead to the types of problems you have. I would take it to a bike shop ...

I did some research and on automatic-transmission models, the most common cause of this problem seems to be a broken or dirty IAC (idle air control) valve. So the first thing I tried was removing the hose from the air intake into the IAC, and spraying Seafoam into it with the engine running. In order to get the engine to run with the hose off, I had to ...

Just had this issue with my 2011 Chevy Cruze. The PCV valve under the valve cover was stuck open. I also had issues with the Idle Air Control on a previous Neon. This was a bigger problem when the A/C was on. But, vacuum leak would be on the top of mt list for things to check. If the car has a MAF (Mass Airflow Sensor) it may need to be cleaned ...

I don't know of any vehicle (as equipped from the factory) that increases the idle speed to compensate for a large draw on the battery. If the alternator starts bogging the engine down then the computer should compensate to maintain the set idle speed but not make it increase. It's easy to find out if the alternator will put out enough current at idle to ...

I have a couple concerns with your plan. These types of lamps (bulbs) are fragile. If it is mounted to your rollbar there is a good chance it will be broken if you do any type of off roading. The most effecient means of powering extra lights is the 12volts of the Jeep. Because of losses in the inverter you will use more power than an equivilent 12v light. ...
