Why does my Oldsmobile aurora idol but wont accelerate


The most probable cause, is its not getting enough of fuel, this may be caused by a plugged up fuel filter. Give it gas very slowly. if the vehicle stays running and revs up its a fuel problem, Check the fuel system and filter. God-Bless!

My 1999 gmc jimmy won't start, it makes a clicking noise when I try to start it and had plenty of juice to battery, is it my starter or maybe my water pump?


No ,the water pump has nothing to do with it , Maybe the battery cable or connections at the battery ! You need to have a technician do a starting system voltage drop test ! Engine Won Start No Crank Diagnosis Troubleshooting Starting System Issues

My 1990 miata is loosing power when i punch the eccelerator. changed fuel filter


Try running some injector cleaner through it , also check to see if there are any air leaks between the throttlebody and the flow meter ( easy way to test is to spray CRC or WD40 at the air pipes while the car is idling, if it revs up while spraying a particular spot, that is where your air leak is.) An air leak between these two parts will let air bypass the flow meter and the engine won't increase the ammount of fuel going to the injectors as you accelerate causing the engine to lean out and hesitate or stall.

99 jimmy 4wd sl trans issue have fwd & rev but....


It sounds like your describing your torque converter and that its staying unlocked. you might want to check your brake light switch/s if they are malfunctioning it could cause your problem. Also possible that your fuel filter and/or CAT might be clogged.

Best thing to do is get the ECM on the jimmy scaned for codes. I believe Auto Zone will scan for free and some transmission shop as long as there honest will scan the ECM too and let you know what you realy need.

The ECM controls the transmission and if there is any conflicts between the transmission or engine the Jimmy will go on a limp mode and your transmission will not shift to OD and may seam to be slipping.

If it is a transmission problem the scan will pick it up, same as to if it's a engine problem.

Good luck and hope this helps, Just trying to save you some money by finding out what is causing the problem.
