Well that car is a obd1. There are many issues that can cause that. A engine that usually misfires or surges under a heavy load or at higher speeds usually indicates it is starved for fuel. I would for sure change the fuel filter if has not been done in last 30,000. I would check fuel pressure and fuel volume. Yes the converter that is clogged causes lack of power, misfire, and poor fuel economy. If the converter is clogged well you still have to fix the problem that caused converter to clog, which is usually an overly rich air/fuel mixture. Most the time it gets clogged due to a bad spark plug, wire, or valve not seating causing raw fuel to enter the exhaust system. I would first check the basics look for any vacuum leaks check the plugs see if they are black and dry (carbon fouled) from to rich fuel mixture, caused by weak ingition, dirty air cleaner, defective fuel pump, e.t.c. or if they white or gray insulator with black or gray brown spots, from low fuel pressure or incorrect timing e.t.c. If you dont find any vacuum leaks bad plugs clogged air cleaner then you need to check the sensors map, mass air flow, etc. I would check your check engine light, when you first turn the key to the on position it should light up, if not than its burnt. Computer codes make diagnosis alot easier. If you can get the codes if it has them let me know. Most exhaust shops will check converter for free. Hope this helps you get a understanding.

Mitsubishi outlander engine backfire when accelerated,cranks normally but does not start


Engine backfire on accel is in most cases caused by ignition issues. Do you have any fault codes in the engine control modules memory, have it scanned.

95 aurora idles rough; runs somewhat smoother as it warms up; yet it backfires if I attempt to accelerate entering expressways. it drives smooth if not accelerating.


We had a similar problem. There was a crack in the air intake plenum gasket. Spraying carb cleaner around it can tell if that's the problem. It will clear up for a few seconds if it is. Not too bad to replace.

When you first crank - it has to spin over engine longer than normal to get started and once warmed up to normal temp it almost impossible to recrank again if turned off you have to try for long period of...


fuel pump, spray wd40 into the intake before trying to start, if it starts right up then the fuel pump maybe the filter needs to be replaced. if it does not then its ignition. but if it starts when cold and then does not when hot, you will notice lost of power and muffled backfires if so then I would rplace the fuel pump. Hope this helps Tim

Outside temp sensor does not work on 1995 olds aurora


You can buy a replacement ambient air temp sensor at an auto parts store for about $10. Its as simple to change as a light bulb and can be found behind your front bumper at the base of the radiator.

96 grand am pop under accelation


Which engine 2.4 Twin Cam or 3.4 V6? The 4 cylinder engine is based on the old Quad4 and I would guess it's either running lean (weak fuel pump) or it's misfiring and you need to replace the spark plugs. Use only AC Delco platinum plugs or it will misfire ( other brands of platinum plugs can cause misfire, especially Bosch). If you have a 3.1 or 3.4 ltr V6 check for leaking intake manifold gaskets.

Hard start when air temp is cold, backfires when warm


Try this, remove (MAF) Mas Air Flow sensor,(be sure key is OFF) so you don't set a trouble code when disconecting wire conector, with some throttle body/air intake cleaner from the outlet side of MAF, spray the sensor clean, let dry, reassemble.Remove snorkle from throttle body, and with a old tooth brush, clean throttle body& plate with cleaner, may take a couple of cans if throttle is badly 'coked' up. Hope this helps.
