    This is about the question above. I have also had 2 1985 cadillacx that both did the same thing for a while and then eventually they would not start at all, and never ever did start again ... i junked them. But the mechanic I had could not or did not know what the problem was either, ever. This is over a couple or years. Could it be the fuel pump at all on all these?

This sounds to be a problem with the ignition module. The module might produce a fairly nice spark at an idle, but at higher rpm's the spark should intensify, if it doesn't then the car will not run at a higher rpm.

SOURCE: Engine Clugs and Sputter while driving up a hill

Check the fuel filter to see if it is plugged.
Remove the fuel filter, and blow air through it in the normal direction of fuel flow. You should be able to blow through it very easily. If it feels restricted, try blowing through it the opposite way, and if there is a lot of dirt coming out, you have found a common cause of this problem. Hope this helps.

SOURCE: the engine seems to be making a sputtering noise

Amelia, we just bought one off a lease 5 weeks ago (purchased from a dealer). We are having the same symptoms, suddenly, as you describe.

Took it back to the dealership. After a bit of drama, they agreed to foot the repair bill ($1000). It was a broken distributer cap and wiring which should have been replaced before it was resold to us. What a pain.

Misfires when cold


Just means it isn't warmed up yet when sputters and misfires. Most likely a bad connection on the temperature sending unit in the engine or that sending unit is faulty. This sending unit tells the computer when engine is warm or cold and has to be functional. When working properly, it tells the computer to put engine in cold start mode, which it is not doing. The sensor is stuck in open position or warm mode and not giving the engine enough fuel when cold making it misfire and sputter. Fix that and you'll have no other problems with revving either.

The PO 316 is still misfires om first 1000 revolutions
so the shop did a poor job for you on resolveing the
cylinder misfires

Try a diffferent shop

Have to clean the MAF Sensor & replace upstream
oxygen sensors if over 100,000 miles

Need the correct oem spark spark plugs/any brand

No reason the gas filter should be clogged unless it was in
the car for 10 years

Fuel pressure should be checked

Need to check for cylinder misfires on a road test of 20
miles or more with professional software in Mode#06

I have a 96 civic ex once the motor gets hot I lose power and it starts sputtering any ideas


Misfires when the engine is warmed up usually point toward an ignition issue.If you have an distributorless igniton system(I think you do),you can measure the ohms across the plug towers on the same coil, and compare it to the other coil(s).If you have a misfire,i would think the check engine light would come on,though,so if it isn't setting a trouble code,then you may have to wait until it gets worse so a code will be triggered.
