I have a 93 Buick Centry with 115K mi. 6 cyl 3.3 L Fuel Injector
For the past 3 months, car has been idling normally, but has trouble accelerating. There is a delay when I push the accelerator and when the car actually accelerates.
The car also has a "choppy" (or pulsating) power delivery and in general feels sluggish. The "choppy" power is usually at low to medium speeds. I don't notice it as much at speeds over 45 mph.
The car has a history of overheating (i've put on 3 temperature sensors, 1 thermostat, several coolant flushes, and 1 new radiator fan). I had a new exhaust put on 6 months ago to replace one that leaked. Spark Plugs and fuel filters were replaced last week and performance has not improved. I also added some fuel injector cleaner to my gas tank to see if that would clear up the problem (and it hasn't).
I thought the problem was with the drive train, but it stalled out on me this morning and the normal idle speed makse me otherwise doubt that.
Aside from getting a new car, is there anything that can be done to fix this?
have the same problem?
