Car bogs down when you get on the gas?

Question

i am looking at buying a car, its a carborated 305 and the owner says it bogs down when he gets on the gas, any idea what the problem could be? I think its the carb but whats wrong with it?

Answer 1

You need to check the overall condition of the engines tune up components. Look at fuel filter clogged or worn plugs and even the timing being off. If it is a high mileage car, then consider the timing chain to be very worn. Put a vacuum gage or timing light on the engines vacuum port. If the vacuum is unstable otr if the timing marks are not steady and bounce around then this is an indicator of a worn timing chain. If this is a 4 barrel carb, then the Rochester Q-Jet carbs are known to have the secondary power valves to be getting blown out by a misfire in the engine. This will cause the bog feeling when you accellerate.
good luck..........

Answer 2

You mean it hesitates when pressing the accelerator? Depending on what year the car is, if it has a carburetor, the butterflies can be sticking, the idle might need to be reset or this can be an early warning of the timing being off. The latter usually leads to a broken timing belt.
If the car has a fuel injection system, one or more of the jets can be clogged. This can be corrected by using a good jet valve cleaner. Follow the label's directions. If that doesn't work after about a month of driving, disassembling of the injectors may be needed and cleaned or replaced manually.

Answer 3

It probably just needs a tune up. I'd get the carb rebuilt, change the spark plugs, distributor cap and rotor, spark plugs and wires and the fuel filter. Also, run some carb cleaner like Berrymans through your gas tank to clean any deposits that may have built up in your fuel system.

Answer 4

Pull your plugs and wires and toss them. you've misfire one a million or extra plugs,that could account for the backfiring,the plugs are not giving goodenough spark to burn the gas on the intake,as well as your wires no longer sending from inspite of ignition gadget you've.Did you cover the throttle body and or distributor with plastic before you degreased it? i wish so, dielectric grease might want to by no potential be sprayed into the combustion, it truly is no longer what's meant use is. After pulling the plugs turn the starter over some seconds, do you nevertheless see moisture on the heads around the plug holes,think ofyou've got easily burnt a valve or cracked a head. make positive you examine your distributor,coil packs, ignition module for any signs and indications of overheating ie: burn marks etc. perhaps you want to take to the storage the position they could ensure what you probably did to thatmotor, as I even do no longer know as you probably did not indicate it, the make and variety of the motorcar. sturdy luck!

Answer 5

It could be the carburetor, It can also be the timing, and it could be that it just needs a good tune up. Change the fuel and air filters first and the oil, if that does not help then go from there. I don't know the year, make, and model, but if it is not smoking and not using a lot of oil then it is probably worth fixing.

Answer 6

First thing I would check would be the spark plugs, if they're gunked up that could be the problem (Not getting enough spark).

Check the points (In the distrubutor), that could be another possibility if they're not getting a good connection.

If none of those work, the carb will most likely need to be rebuilt.

Answer 7

needs new carb..check timing and is it tuned up. almost never worth messing with a carb. unless youve done it...by the time you do it you wasted time and money and it still may not be right... I know.

Answer 8

the carb might need to be rebuilt,or you may need spark plugs and or wires or distributer cap and rotor or the timing may need to be adjusted ...if that don't work,try a new timing chain....
