I have a 1996 infinity I30. When I accelerate the engine feels like it hesitates and I hear a bit of a backfire. At idle, it feels rough. Once I get up to speed, it runs great. I have a 116,000 on it. Can anyone steer me in the right direction as far as what I need to start looking at? The check engine is not on. Any help would be greatly appreciated. My mechanic wants to go by the process of elimination and that sounds very expensive.

sluggish performance by jhayes9835

This is what has been done so far. My mechanic changed the plugs, flushed the fuel system and changed the fuel filter. That was a cost of 300.00 and I told him to stop there.
I still have the problem. If you ease into the accelerator, the engine is fine. It is only when you punch it or try to take off quickly when the problem starts. Also, I can feel it hesitating a little when I am going up a bridge (under a slight load). Hopefully this better explains the problem. Your help is greatly appreciated.

I had all six coils replaced, ran good for awile, started running sluggish again. Changed the maf sensor, no improvement. Injectors check out, I had an AIS flush.I am at a loss. What else could be wrong?

have you changed your air filter? check to see if its super dirty, its right above the battery you'll see 2 small clips holding it in place, just pull it back and up. do you have any cracks in your muffler? when you turn your car on and walk behind it do you smell a lot of gas (more than usual)?

even check for bends in the pipe cause if its not complete round the air won't flow smoothly and you'll feel it maybe jerk and that u have to press a bit harder than normal to speed up. If your problem went away when you changed the ignition coils then it could be your spark plugs right under each coil. usually u change those with your iginition coils. do you have a light on in your car? cause if the problem starts with starting your car it could be the flywheel or solenoid or p0355 error code which is a sensor that tells your car how to start it. could be a lot of things man, tell me exactly how your car runs and if it makes a loud noise starting up in the cold after leaving it a whole night. i'll try to find out what the problem is.

I had the plugs replaced, injectors checked, maf replced. There is no exhaust leak and I had the fuel filter replaced when I had the ais flush. There are no codes showing and the car starts up fine. I do not know what else to do or what else to check. Any further help is greatly appreciated.

Did you change the air filter with the MAF sensor? Need to put in a factory OEM air filter ($8) with the new MAF. Some bulletins say that after-market air filters still mess up the MAF. I don't believe it but I changed it as I didn't want to take a chance since I spent about $170 on the whole thing.

I have a 2000 I30 last summer SES light came on and threw a P1320 Code it would come on and off. Winter time came the SES light went off and stayed off all winter approx 7 months and yesterday we got up to 60 degrees and the SES light came back on. You start the car and when you first start driving the car chugs and then seems fine. Than when on Freeway on cruise you get a jerking feeling every now and then. Anybody come across anything like this????
 
 I dont know what to change first: Fuel Filter,Coils, Speed Sensor,MAF??????
