idle problems
I have a 1979 rx7 and i cant start it with out useing the choke even when its warm outside? anyone know what could be causeing this ?

hard starting when warm is usually an indication of lean running conditions, especially at idle.
check the spark plugs, if they're a brilliant white there is not enough fuel, if they're black you're getting too much fuel, you want them to be a nice golden brown. I strongly recommend a wideband o2 sensor on all carburetted vehicles. Could be a massive vacuum leak. |
is this a cold start?
|
hmmm I'm go check those then and buy a hose and replace it... yes a cold start like even after using the choke at some stops it will stall out
|
I'm new to cars what is o2 sensor
|
it's located in the exhaust system near the engine and used on fuel injected cars to help control fuel mixture.
|
Thanks man Im just replace that and vacume hose think that might solve the problem?
|
what if the o2 sensor is bad
