I have a 1985 Volvo 244GL 2.3L. The main problem I have is very hard start when the engine is cold. Its been get worst over the last 5 days (before which I have had no problem - even through winter - now its pretty warm around 45F). I have to give it gas for a long while or the rpms get too low and it stalls. If its only been sitting (since last run) for an hour its not a problem but in the morning and after work (8 hours) it does it again. It also has been idoling pretty high somtimes...not very often it will sit at 2,000 instead of normal 1

The other complaint I have is a hesistation I have when accelerating or going up a hill. What I mean is it will have power and then it stops for about a second or two then picks up. It creates a slight rocking motion. This happens all the time but mostly when its cold.

I figure its a fuel problem, I just changed the fuel and air filter, the oil and check all fluids including transmission. Im not sure where to go next. Please be as detailed as possible in causes and fixs.

I can't tell you how much I appreciate any help - Justin

 

You need to try to install a fuel pressure guage and monitor the pressure.Whe it sits overnight and when you have the hesitation.

 

Can I get one/install it myself? I have moderate experience with car repair.

ts been getting worse...no its very jerky and much more often. It can be doing it for about 20-30 seconds straight

Worse when the car is cold and always when accelerating or going up a hill

Thanks for the help - Justin

 

Yes you can buy one and install your self.
But you need to make sure you get the one to fit your car.
