Holding back

[obews]

Hi again, my new problem is on my 03 1.8 Vectra - I had it out a run today and decided to give it some welly but just didn't seem to want to take throttle - holding back definately.
Running away fine and going good but when you try to floor it just feels like it's not getting the fuel ??? or something. Have read about egr valve cleaning - could this cause it ?
104,000 mls

Also noticed that it's taking a good few turns to get it started - used to fire up right away, also the idling is feeling uneven !
Some advice lads ?

coil pack?

A bottle of injector cleaner in a full tank of fuel then a new Fuel filter.

Would this cause the high revving when started ? I have seen a lot of fault code readers on ebay but can anyone advise me on which one to get - just a basic one that can read and clear the faults.

Well folks just got a shot of a code reader from my cupboard - forgot that I already had one !!
2 codes came up - P0170 FUEL TRIM MALFUNCTION (BANK 1)
P0335 CRANKSHAFT POSITION SENSOR A CIRCUIT MALFUNCTION
Now can anybody translate so that I know what to look for or what I need to replace, please and thankyou.

Have bought a set of spark plugs,lambda sensor,maf and a new fuel filter - don't see an egr valve to clean. Is there any other parts that would need to come off and get cleaned ? If so please tell me where they are and would I need or be better replacing the coil pack too ? Cheers.

Did you sort the two faults identified by your code reading?..

[obews]

No thought that doing these things that would sort it !!!
