While in there rule out any leaks in air cleaner and wiring connections, You will get a check engine light or code that may help if this continues, T steve01832 Veteran Sep 19, 2006, 12:02 PM Post #3 of 3 (1832 views) Re: 89 mercury topaz jerking Sign In You may want to start by doing an exhaust backpressure test. If the converter is clogged the vehicle will not accelerate. Also check your EGR to see if it's hanging open. If these aren't the culprit, post again with more info about the car.   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
