It would continue intermittently but only at speeds over 55. I added gumout and heat water remover because I had fueled up about an hour before this happened. Then I had the fuel filter replaced today. It was running smoother but then started again but not as bad as before. No codes come up when they checked it on Sat to see if anything was wrong. On vacation and would prefer to get it done at home if it is safe to drive at 55. kev2 Veteran May 27, 2014, 9:48 AM Post #2 of 5 (1070 views) Re: 2003 Venture bucking when going over 60 mph Sign In you used a scanner to check for codes? I ask because not all readers will read all codes. It happened AFTER fill up- is it safe to ASSUME that that fuel is gone and time for a refuel ? Nothing I can recommend for a quick look - does the use of AC have any effect? hills - going up make a difference? you are NOT towing? around town - select 2nd and see if the issues return with the higher RPMs. Hammer Time Ultimate Carjunky / Moderator May 27, 2014, 10:47 AM Post #3 of 5 (1065 views) Re: 2003 Venture bucking when going over 60 mph Sign In If you get it hooked up to a professional scan tool you should be able to get misfire data from it in mode 6. You probably have a coil going out but you will have to determine which cylinders. You didn't post your mileage but if it's over 70K, it's time for plugs too. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional. j2nthai New User May 27, 2014, 12:13 PM Post #4 of 5 (1053 views) Re: 2003 Venture bucking when going over 60 mph Sign In thanks for the feedback. No difference if using a/c and have 132,000 miles on it. not sure which scanner he used but plugged it in and kept it plugged in as he took it out on the road. Even had it plugged in while it was bucking and no codes came up.

You're looking at misfire tracking data. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.   Email This Post   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
