Always seems to run fine in the mornings when the engine is still cold but after 10-15 miles of driving it starts to cut out. Had an O2 sensor replaced a few years back and can't remember exactly but I feel like it started as a similar issue. But from what I remember of that it was like there was no power at all when accelerating. Could this possibly be another sensor problem, bad plugs or wires, or catalytic converter or am I way off with any of these guesses?

You can still get codes from this to help narrow it down. It can run fine cold if you say so. By "cut out" do you mean engine stalls, runs rough, misfires? Tach jumping only when this happens? T CMQ User Oct 9, 2013, 1:17 PM Post #3 of 6 (1333 views) Re: 1994 Bonneville cutting out when accelerating Sign In The tach only jumps when it's doing this. I would say it's almost like it misfires. Had an old Chevy pickup that would miss from time to time and it feels similar. But that was an old carburated motor. Not sure if it's the same situation with a fuel injected motor. Bad injectors or something along those lines maybe? Haven't looked at the plugs themselves but all the wires are in good shape. The plugs themselves are in hard to reach spots without having the right ratchet and extensions.

It will set a code when you do that so don't panic about that. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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.

Plugged it back in and drove 30 miles with no troubles. Started up this morning and drove 15 miles and it cutout a couple times and the check engine light came on but never had any problems after that. Does this mean problems with the MAF censor or just a computer error code type of fix? Hammer Time Ultimate Carjunky / Moderator Oct 10, 2013, 8:21 AM Post #6 of 6 (1301 views) Re: 1994 Bonneville cutting out when accelerating Sign In It could mean that. The fact that things changed when it was disturbed could mean the sensor is the issue but nothing is confirmed. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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
