Hello and Welcome to Just Answer!

My name is XXXXX XXXXX I have been working on cars for over 10 years.

Is the check engine light on?

Are there any codes in the computer?

What is the engine vacuum at idle?
Customer: replied 4 years ago.

the battry light is on


What is the battery voltage at with the engine running with the battery light on?
Customer: replied 4 years ago.

the battry voltage after we jumped it the short time it was running about one minute the battery reading was 9.6

Ok... 9.6 is way too low. If the battery is good and has a full charge, then this could be a bad alternator. But a bad battery will also do this as well.

We should fix this charging system first before we get into the performance issue. This might just be the problem.

If not, then we will check the fuel pressure, tune up parts and engine compression.
