hi, i got a 2 litr engine and it it feels like its missing a beat like thud thud thud, the revis bearly on and engine barly ticking over.

prior to this the immobliser had packed up on it and i had that changed. the carthen backfired. i thought it may have been the timing beltmisalligned from thethat so i changed thatbut stillno change.

i thought one of the cylinders might have bentso i changed the whole engine. still the same problem. need help and ideas??

 

are all the plugs fireing ??

 

as far as i can tell yes,woundering if my fuel was contaminated?? ?

 

its possible if u kept your fuel in a container that wasent made for gas....
