1991 240 volvo with around 90000 miles
Has been running fine for the past two years and just recently began go give problems.
Symptonsm
1. Car always seems to start with no problems.
2. At times the car seems to run with no issuse.
3. the idling is fine upon start up HOWEVER after revving the engine then very rough idling .
4. at times it has no power and will not accelerate. take a long time... two or three minutes to reach highway speeds. There is incremental acceleration when pressing hard on the accelerator... Meaning that went you press the accelerator to the floor there is a small increase in speed. Pressing the accelerator to the floor again yields another small increase in speed.
please advise
