coupe Posted June 17, 2005 Share Posted June 17, 2005 I have a surging prob in the vortex. Its very slight but noticeable as you cruise. All the leads ,plugs, fuel and air filters are new the timing is set right,all connectors are clean and siliconed,and theres no fault codes showing. I only run 95 ron or 98. Any ideas why :?: Quote Link to comment Share on other sites More sharing options...
Ross Posted June 17, 2005 Share Posted June 17, 2005 I would check your oxygen sensor and knock sensor first. Quote Link to comment Share on other sites More sharing options...
john in KY Posted June 18, 2005 Share Posted June 18, 2005 Clean the throttle body and all its passages, the IAC and all the engine wiring harness connectors. If nothing improves think about having the injectors professionally cleaned. Visit http://www.xt6.net for more ideas. Quote Link to comment Share on other sites More sharing options...
4WDFrenzy Posted June 18, 2005 Share Posted June 18, 2005 I have but one thing to say,"Fuel Pump." It is sad but true. Most of the time if it starts to surge while cruising, the fuel pump is on it's way to the retirement home. Try changing it out. Mine stopped surging once I replaced it. Just beware of the "gasoline bath" that comes with the territory. Quote Link to comment Share on other sites More sharing options...
