I have a 1995 auto. As comes the cold weather, comes some problems. There is a noise when I accelerate now. It sounds like it is coming from the exhaust. It is more of a rumbling noise. You hear it mostly before the car is fully warmed up.

Well, even after my car has warmed up, my pick-up is pretty bad. It seems like I have lost all low-end power til ~3000rpm. Anyone know what could be the problem? I have no CEL's. It all just started happening about a week ago. Any insight will be appreciated. Thanks

 

i sorta have the same problem with mines, but i think its my rims.. not to sure..... mines just feels really really sluggish. till around 3000rpm... i dunno what is causing it....

 

I would guess the knock sensor but I dont think it would make strange exhaust noises. Anyhow the knock sensor doesnt trip the cel, you have to get in there and check it yourself. Do a search on how to check the ecu for codes.

 

I have the same problem, I checked the knock sensor and it was bad. I am getting one this week, hopefully that will solve the problem.

let me know how that turns out, my car ran perfect, then i got into a slight accident, i just needed to change the hood an the Air condition condenser, but after the accident it started running like that, i dunno if it would be the Knock sensor, concidering my car just broke 44,000 miles. But let me know how it turns out.

 

oddly enough my car was hit (and run) about a few days before the problems started.. related? the damage wasnt extreme, dented fender, scratched bumper, busted light corner light (all on driver side)

 

same problem w/ no low end power or same problem with the sound also?

 

Same problem with low end power, no noise problems though.
I hope the knock sensor will help I will keep you updated.

checked codes.. 0505 no error. no knock sensor problem. must be something else.

 

are u using cheap gas?

 

How much does the dealer usually charge for a knock sensor?

 

NEVER. Not since I got the Max 20k miles ago. Always 91 octane or higher.
