Go to *** (three stars) which is the last paragraph to read the direct answer * Have you checked your ECM? Many times a failing engine control module or ECM can give bad readings about an engine's performance. Many times this leads an owner to purchasing parts you may not need (i.e. distributor, coil, injectors, O2 sensors, ISC (idle speed control, idle air control), ISS & CA sensors). If you have a car manufactured between 1985-1999, your engine management system ECM(s) and body control computers may have a higher propensity for failure and may fail eventually. This is likely due to several factors including the mounting and location of the units, and a critical implementation and utilization of internal components including several models of electrolytic capacitors that have proved to have inherent intolerance to heat.The main cap manufacturers were Rubycon and Nichicon. "Normal" usage included the mounting location of the units which often meant the components in over 100F temperature sometimes. The current through the lands of the units also led to many problems that have been occurring separately and some indirectly affecting other controllers with adverse affects. The caps often will intermittently loose there ability to function properly such as storing a voltage charge for future use or providing a clean voltage signal for proper operation. Eventually they can lead to other fatal malfunctions of other components including injectors, coils, actuators which can in turn be another diagnostic nightmare. These components were used by the millions in hundreds of applications by among others: Mitsubishi, Lexus, Toyota, Honda, Acura, Ford, OKI & Kefico in the manufacturing of their ECMs, PC's, TV's, DVD's etc.. ** The dealership cost on these units is anywhere from $650-$2000.This doesn't always include reflash when needed or key/security immobilizers and transponders which are the new very serious and potentially very expensive reality. Before you spend any money, consider a second opinion on the diagnosis. We have been rebuilding, testing and selling ECMs over the Internet since 1997.Many of the units can be tested by out technicians some in actual test cars! When available a repair or replacement service can be applied. If you would like to locate your unit to have your ECM tested or serviced, follow the upcoming directions or call toll free for assistance at 1-TRIPPLE "8"-ECM-ToGo 1-888-326-8646 or direct (Houston Metro) at 281-922-1900. If you do not see your year or model, please contact us and we have a computerized system to tell where every computer is located on all vehicles. We can then evaluate which product will best suit your needs and your budget or that of your customer. OPENING THE ECM FOR EXAMINATION: IMPORTANT NOTE:In some rare cases it is better to leave ECU removal to the professionals due to some labor intensive mounting by some "ingenious engineers". Our recommendation is if you are not the mechanic, get a price to remove and then re-install the ECM after servicing or replacement to determine if it is in your time/financial budget. For you mechanics and DIYers, however it is relatively easy to find and remove most of the units yourself. It is usually safe to open the unit which is also very easy (accept the Chrysler/Mopar units or gel filled sealed units). When you can gain access to the inside of a unit, this will allow you to look and smell for burns or corrosion. If you see nothing, it does not necessarily mean you have no problems, but it may help you verify your diagnosis if it is. You may put any personal I.D. marks on the unit before sending it in if it makes you more comfortable. All units determined not repairable will be returned to the customer upon request at owner's expense. If you have any questions, please call us toll free 1-888-326-8646 1-year warranty on all rebuilt ECMs How to remove the ECM engine controller: *** Be sure to unplug the battery terminals before removing unit!!! The ECM for engine control is located under the console area near the firewall of engine compartment inside the car. To find it you must remove the small plastic decorative caps and remove the Phillips head screws on both sides of center console area. This area is under the shifter and emergency brake. After removing screws from both sides, remove the trim panels on both sides to expose the areas under the console. Now look toward the front of the car in the center, under the stereo & A/C area of dash. The ECM is sitting upside-down with 3 plugs in it. It is gold in color and the size is approximately 6"x5"x1.5". You will need a 10mm or 12mm socket or wrench to unscrew the 3 fasteners holding the ECM/ECU in place. It is in there tight, so take your time. To remove the 3 plugs connecting the ECM/ECU to the wiring harness, you must depress the small tab in the center of each plug and pull down or in an outward motion.
