My car loses power momentarily on accelerating. It shudders a bit?

Scan for codes and check the fuel pressure with a gauge auto parts rent it.

Okay. If read it, could be timing chain or camshaft position sensor to? Hopefully not a big job as just bought the car

Hi LOUISED85,

If the check engine light is not on then it could be the crankshaft angle sensor which has a history of failure on these cars. The tough part is when this sensor fails it may or may not set a code. Here is a guide on what to expect when changing the sensor

The engine is different but the procedure is the same,

The location of your sensor is the right side of the engine block look for a three wire connector

Please let me know what you find.

Best, Ken
