Not a problem, Is this problem occurring when r in gear or with it in park?

Will it drive normal in gear?

Customer: replied 1 month ago.
No. it can not drive because rpm can not go up. it driving but very slowly.
Expert:  Ron replied 1 month ago.

Okay I understand now, the first thing I would do next is connect a fuel pressure gauge and read the fuel pressure. If you can get this done for me and post back with the results we can work from there.

ok
Expert:  Ron replied 1 month ago.

Im here all day. Let me know.

Customer: replied 1 month ago.
It is about 65 psi
Expert:  Ron replied 1 month ago.

That is with in the normal range. The next step then would be to check and see if you are dealing with restricted exhaust. Are you able to run a back pressure test on the exhaust?

Customer: replied 1 month ago.
i will try
Expert:  Ron replied 1 month ago.

If you do not have a gauge then the other best way to do this is to loosen the exhaust at the manifolds on both banks till you have a healthy leak and then see if the power returns.
