Engine Run-On

hi im just wondering if anyone knows what my problem is...when i turn off my car most of the time it will run on almost like sputtering or something. It varies from 1-5 seconds and can get quite "violent". Is it the timing belt or what? I really dont know much about that part of my car so any help would be greatly appreciated.

Could be that its not closing the fuel/air delivery properly. Bad gasoline would do the same also if your engine has lots of carbon build up, it would do that.

well what do you reccommend i should do to try and fix the problem? it has a carburator so would that change anything?im guessin you probly already knew that tho:o

Weekend is coming.

Drive to Hull as fast as you can and party.

Should blow off some of the carbon.

(Try a nice long highay drive with some fuel injector cleaner added to the gas, Toyota's is best.)

I tend to do alot of highway driving anyway so i dont know if that would help....so does everyone think that its just excess carbon or is there another problem that could be causing this to happen???

Come on guys i need the help:(

Timing out of whack?

i dont think its that becuase it runs perfectly on the highway etc...it only does that when i turn the car off...it also hesistates and almost stalls when the engine is cold. I also noticed that it wont shift into 4th when the its still cold...once its warm its fine. Anyone have any idea...its really annoying and im kinda scared it will break something expensive :mad:

It's called dieseling. My old mustang used to do that.

thanks alot ill take a look:thumbup: but i still dont know y it almost stalls when the engine is cold etc....any help with tht?

Actually, it occurs to me that you may have a problem with running too rich. To me that would explain both the stalls when cold and dieseling after shutting down. Dunno what the cause for that could be, sorry :(

Anybody think this is a possibility...im running too rich? and if so how do i fix it?maybe thats y i have to put gas in quite often:disappoin

if you got a carb chances are your accelerator pump diaphragm is broken :rolleyes:

ok well first of all id like to thank you guys for all the help...but no one has told me how to fix the problem...only what it could be...im not a mechanic.....yet:p so i still need help.

Well when someone says what it could be, go look at that part and maybe take it apart, see if it looks messed up. Take apart your carb and see if your diaphram is broken like Flashm said. If you don't know how, then get a manual, they also have trouble-shooting sections that could help you. :)

I bought one off ebay...just waiting for it to be delivered. lol
