My 2000 volvo s40 sputters and bogs down as i accelerate. The engine also starts to shake the faster or harder i try to accelerate. The Check engine light flashes. Sometines the light turns off when im at...
ok everyone not trying to be unappreciative of your input and ideas however only w couple of you are even looking in the right area. generaly when your check engine light comes on its telling you your car is misfiring (obviously). its basically a caution light not so much a stop pull over and run type of light. yes you can damage your cat over a prolonged amount of time with no repair. so my thoughts on this are that is has to be the ignition coils. I drive a 90 vw and a 96 monte carlo. i just recently had this issue with my monte and first thing i did was replace the coil packs (ignition coils). result...light went out and not flashing or anything and perfermance is restored, all is well and it runs great. give that a shot, im 98% sure that will take care of your problem, and in your s40 there should be 2 coil packs, typically only one is bad but im that type of guy who doesnt wanna worry about the other one at all so i just replaced them all. they're typically around $50 each. my monte was $36 for 1 and there are 3. your s40 will only have 2 and there located directly under the plastic cover on top of the motor. hope this helps, good luck and dont waste your time searching in the wrong placed, check engine lights are usually sensors of an ignition misfire so if your not sure which one then just limp the car down to autozone and have them plug it in for free.
