Question about 1994 Oldsmobile 88

2 Answers

Slight miss when pulling out and light acceleration.

When I start out driving, I accelerate lightly and it doesn't seem too bad, but when I 'm coasting (at any speed) and I give the car light acceleration it seems to have an intermittent miss. This also happens at highway speeds and is very annoying not to mention poor gas mileage.

    I'm having the same problem but at idle it will miss and when accelerating the car shakes like it is going to fall apart. As soon as im costing at a steady speed the car feels fine.

    I still have the same problem with the "slight miss". Now, I have a high RPM idle when I start the car when it's cold. I have tried to unplug the TPS connecter and the maf sensor ( even though the "check engine" light comes on) but it doesn't reduce the problem. It eventually dies down to regular idle but when I give it slight acceleration I still feel the "fish-bite" -- "surge" and it does that whether it's cold or hot.



    Could a Crank Sensor/and or/ Cam Sensor be causing this? I was also wondering if there was a thermal sensor (just below the maf sensor ) screwed into the water jacket that's faulty?

    Took some GUNK engine cleaner and my pressure washer (Since it was a nice day and the engine needed a bath) afterwards drove it and the next few days it went away. Must of been "cheap wires" I put on about 2 yrs. ago.

P.S.....I 've checked the plug wires, coils and plugs. I also looked for bad , broken , or loose connections.

You probably have a bad coilpack - but lets not guess...
Take a voltmeter and check the resistance of the secondary terminals on the coilpack. These are the terminals under the plug wires on the coil. only remove two wires on the same coil at one time. check the resistabce on the terminals and it should be no higher than 15000 ohms. if you see any black powder or staining on the coil terminal when you remove the wire from it then you have to replace the coil AND the wires. don't waste your time replacing one without the other if you see the black under there.

Here is another test for bad wires. take a windex bottle of WATER and a tablespoon of table salt in it. start the engine and spray the plug wires from the coil to every plug you can get it on. turn off the lights arround the car so it's dark. look carefully and check to see of you see any arcing. this looks like mini-lightning bolts. look closely. Good luck...Scott

you have an engine miss, any time the check engine light starts flashing the engine is missing, should be an easy fix sounds like either a bad spark plug or a bad plug wire if you have the codes checked there should be a code telling you what cylinder is missing, but if i were you i would tune up the engine all new plugs and wires and filters......GOOD LUCK

Maybe the timing is off, could ir be that you accidently moved the distributor while replacing the cap and rotor? If you have acces to a timing light give it a try. Good Luck.

If the light is flashing it means the engine has a misfire that can damage your catalytic convertor which is very expensive. A tuneup might be in order if its never been done, but I have personally seen many bad timing belts and fuel pumps that have gone bad on those vehicles also.
