Hi all,

Yesterday, When i finished rebuild my engine i drive the car and it was ok but when i refuel it with a new fuel ( 98 octane gaz ) then i want home to wash the car , after 1/2 hour from washing the car i drive it but it was too bad and i see a back fire from the exhaust .... <img border="0" title="" alt="[Frown]" src="gr_sad.gif" /> after 2 hour every thing came back as good as it was befor ... and no back fire ?

So what is the problem in your opinion ?

Thank you
Adnan

 

Sounds odd....wonder if you got some water into the intake or air filter?

PS - How much is 98 Octane gas in Kuwait? About 35 cents a gallon US? <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

 

In kuwait $ 0.3 per liter .. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

I think no water into the intake or air filter ,coz after 2 days the car go bad ( back fire )and after 1 huor every thing came back as good as it was befor ... and no back fire ?

So what is the problem in your opinion ?

 

Usually a backfire has to do with timing somehow. Maybe you have a loose connection on your cam position sensor or crankshaft position sensor?

PS - Send me some of that gas!

 

Exactly the back fire it's come win tha car is cold and after 2000 RPM , and after 1/2 hour every thing came back as good as it was befor ... and no back fire ?

 

Im droolin over how much compression I could run with that gas on a daily basis <img border="0" title="" alt="[Razz]" src="gr_images/icons/tongue.gif" />

 

Where can i find the cam position sensor and crankshaft position sensor ? (if you have pic plz)

 

Cam position sensor is behind the intake and mounted to the block. It is a flat connector with a 10mm bolt holding it down.

The Crank Position sensor is just above the starter. You will probably have to drop the starter to get to it. Also held in place by a single 10mm bolt.
