Another question?
 

Also something not good is happening after driving the car for a while after it heats up it starts bucking like a bronco in a rodeo at lower RPMS. I have no idea what it could be also I am feeling a lot of heat coming from my gear shifter in the car is it over heating and maybe the temp gauge is not working can any one tell me what could be causing these problems the car has a R154 transmission in it I just replaced the clutch and flywheel so that should not be causing the problems .I am at my whits end somebody help please

check your tranny fluid mabey its leaking from bad seal

I changed the seal when I replaced the clutch.

Doesn't mean it can't leak or couldn't have gotten a tear when it was installed... Did you replace the seals on both ends?

No we did not replace the front seal.But we inspected them closely and I have been checking the dust cover where the seal is located.I was leaking gear oil but it was not coming from the seal we thought it was but upon closer inspection when we replaced the seal we saw that it was coming from the rear speed sensor so we replaced that also. I put in lucas 80 W-90 gear oil. The flywheel is a spec lightened flywheel the clutch is a zoom stage three clutch we replaced all the bearings when we replaced the clutch. One thing that I did after this happened there was no fan shroud on the car so I put one on, dont know if the engine was not getting cooled enough. Also AFM sorry I am not sure what that stands for I asume it means a piggy back ecu if it does I am going to have a map ecu2 installed also a msd ignition box.Also I figured one thing out the gas gauge is not working correctly I put in some injector cleaner before this happened it was supposed to treat 20 gallons of gas,well my gas guage was saying that I had almost a full tank when in fact I only had about two gallons of gas when I put it in, and I drove the car that way.any other suggestion. Thanks guys for your help.Hopefully it is something small and not major.

wouldnt that be bad for the injectors because of the concentrated formula?

Thats what I am thinking I just drove the car again today and it did run better. tranny still getting hot and stalling when the engine is hot but not as much bucking as a couple of days ago still some but not as much.

Check your ignition timing and mechanical timing. A slipped timing belt could cause these issues.

Cool thanks I will check the timing.
