...same problem. Catalytic (?) converter is plugged. ...car will likely start and run, but will seem to be underpowered - especially under accelleration. Check Engine light may come on, but not stay on - which may post a "mis-fire" code, or a transmission shift cellenoid code, or maybe no codes at all.

Cat. converter is warrented for 8 years or 80,000 miles, whichever comes first. Take the car to a dealer.

I had that problem. It is a bad catalytic converter. If your car has less than 80000 miles it will be covered by your dealer.

I have a gti golf problem is loss of power when pulling away then it will go ok when you put your foot down ive changed fuel filter x air flow meter it goes better but its still not right


Could be several things, weak fuel pump (failing), , or fuel pressure regulator ,Often, the engine will stall out during a fast accelerating, or suddenly jump and accelerate more quickly than you intended. It also might take more effort than usual to get your car to accelerate, and when it does, the acceleration will happen much more slowly than normally. if you have bad plugs or wires. good-day!

ive had the same problem with my 02 dispatch 2.0hdi. would start ok on cold but after a run and getting the engine hot it would take a few tries to start. then one day it just wouldn't start at all. turned out to be leaking injectors. replaced the copper washers and plastic sleeves, put it all back together and it was all sorted.

Ford-F350 7.3 turbo sluggish when you accelerate


i dont know about the turbo going bad,but i do know that ive seen 7.3 diesel have bad injectors,usually 2 at a time, check for fuel at the injector which can get messy so wear protective gear such as goggles and gloves,while running crack open the fuel line at the injector to see if there is fuel,it should run rough which is good on the working cylinders,if it doesnt change then maybe a bad injector,or not enough fuel pressure at that injector.injection pump issues are another thing,but most likely its an injector.

Charade Runs rough at low speeds


Couln't hurt to put a bottle of fuel injector cleaner through it. If that's the problem you should see improvement in just a few minutes. Could be air intake. If the filter is very old or if it is after market and there is not enough air already filtered when you press the accelerator there is a lag. You need a certain amount of space between the filter and the connection to store air for immediate response. Good luck.

Does not chilarates...


OK, I've stopped laughing...chilarates??? Do you mean accelerates? If so, check cat converter to make sure it's not obstructed internally. Before changing pumps etc, do some pressure tests. Also, some of these engines had soft keyway slots in the harmonic damper pulley which enlarge and mess with timing. Sometimes you can detect a wobble there or it has to be removed and checked.
