HELP!! Gen 3 missing after extractors been fitted

[pha7ss]

hey guys i have just had my x-force 4 into 1's fitted by exhaust shop fitted very well and sounds and runs great, only problem is that now when i sit at the lights at normal running temp and in Drive it skips a beat once or twice in a light change, checked all the vaccum lines and spark leads ect injectors are fine, have just bought 2 new NGK/NTK Oxy sensors today fitting tomorrow

not sure what could have caused this just by fitting extractors, anyone have any ideas ??

maybe spark plugs

Check your spark plugs can be damaged when fitting extractors if not new O2 sensors should fix the problem

ok I'll check the plugs tomorrow. She runs fine maybe needs a tune. But trying to find something simple that would of happened during the install. Thanks for your replies

Plugs are very common to break when fitting extractors. Or a lead isn't on properly.

Don't fit the O2 sensors for at least a couple of weeks to give all the impurities on the inside of the extractors to burn off or they will only contaminate the new O2 sensors again.
