Sounds like a blocked catalytic converter blockage .Do a exhaust back pressure test to confirm this .Is the check engine light ON when the engine is running ,Looking at the parts replaced i take it it was done because of malfunction codes found ?What is the fuel pressure at idle .Rgds Greg

Fuel pressure at idle is 39. Done back pressure test it was good.It had code P 0300,0304,0301,0446.also replaced the fuel pressure regulator. Cleared all codes and now it has no codes but still the same issue. done a compression test and all cylinders where good.

With engine off disconnect the MAF sensor and start engine and then try to drive ,Do you now have a bit more power with the MAF being disconnected.. Greg

It was worse. It didn't want t start. Once it did start it wouldn't hardly idle.

Now check for codes you should have 1 MAF code . Greg

Just checked and it had a p0102 and a p0113. Cleared them, rechecked and no codes.
