hey guys,everything time i come to a complete stop my engine keeps knocking like it want to keep moving forward, why is this coulle it be that i have bad radiator, any clues?

 

Say what?

 

yeah...wth are you talking about?

try holding down the brakes a little harder?

 

Perhaps, you mean the engine rocks forward and back and you think this may be caused by a bad radiator support? If this is the case, you'll have to get out there and check to see if you have a bad motor mount or something worse... First thing you should do is clarify your question so members can actually help you with your problem.

 

i don't know how to clarify, but from what our saying its pretty accurate, it does move forward and its only happens when im at a complete stop, like waiting at a red light

 

Push the clutch in or put transmission in neutral.

What are the conditions when this happens.
1 are you auto or 5 speed?
2 are you in neutral?
3 clutch pedal pushed?
4 Is it knocking after you shut the motor off?
4 Is it noisy or rough driving in any gears?

Your description is not enough for a diagnosis.

 

OK
1. my car is automatic
2.no
3.no
4.no
5.no

 

ill try to post a video later

 

Iv'e never heard of a Max doing this, But I know that old Chevy cavaliers and celebrities had a sticky TC lockup solenoid that would not allow the Torque converter to disingage. stopping would be like stopping a 5 speed in gear. motor would lug and stall.

Can any one tell us if the TC lockup has its own connector to unplug for testing purposes??

My dads old jalopy had a toggle switch so he could turn it on on the highway, and turn it back off 2 miles before town. Its ghetto but it works.

 

your very smart, when i look under my car their is a wire where a plug used to be and it has been ripped or cut off, the plug is on the passenger side right next to the alternator and timing belt maybe that is my issue, it seems like it miss firing or maybe a coil is bad, i have no idea but i appreciate you trying to help thanks man

 

When your stopped, is the motor still running and just bucking/jerking? If so you have a bad misfire (ignition coils most likely).

TC lockup wouldnt allow it to run at all.

Not that smart, just gifted with a mechanical mind.

 

yea exactly, im getting bad mpg cus of it to i need to replace it or infact just get a tune up

 

Follow that wire and take pix. Left front O2, or crank sensor would either cause crappy running or no running. Disconnect one coil at a time till you find the missing cylinder. The good coils will cause a drop in rpm, the dead cyl will make no difference cause its already dead.

Do you have an engine light on? What are the codes?

 

ok ima take a pic first thing tomorrow mourning the codes that are coming up are.

1.P0400 exhaust gas recirculation A flow

2.P0135 O2 sensor heater circuit bank 1 sensor 1

 

yea my car is running crappy it hesitates a lot when i accelerate
