Is there any-body out there that can help pleez.

Since i've had the car (18 months) it has had an intermitent starting problem from hot and cold,engine will turn ok but will not start, now it has developed another problem, it is ok from cold but as it warms up, it will start to hesitate and hold back( just like it's got crap in the tank)it will also pop on the odd occasion (not back fire). There is no fault code displayed when reading the ecu, and no check engine light. The spark plugs are new (approx 200 miles) , i've checked HT leads, these read betwean 10K ohm and 12K ohm (longer lead)

Any help greatly appretiated
Thanx Stu

 

try entering "hesitation" in the search engine & that produces loads of results.
The popping in un-burned fuel in the exhaust & is often heard after exhaust mods (decating) & is generally nothing to worry about.....mine does it & it sounds cooooooooool
