Back firing out of the intake is because the valves/cams are not set right. When you did the timing belt . did you set the crankshaft mark at top dead center of the compression stroke. If it's at the exhaust stroke this would cause backfiring and violent shaking.

    has a timing chain, is set to tdc, i changed the camshaft positioning sensor and it stopped the backfiring, but still lets burning fuel out exhaust during stroke, so i think the synchronizer is bad because the chirping stopped before gas milage startd sucking and engine blew

It was running great and started backfiring through the intake. Just had a valve job with new valves, valve guides, springs and a new rocker arm assembly. New point, rotor, distributor cap, and wires.


recheck the valve clearance when the engine is hot if it is hydraulic operated then thee will be an auto adjustment but it should be around .010 " when stationary and hot

My 84 f350 is having fuel and air problem. It ran fair but it would backfire when i let off the accelator,so I had the carb rebuilt that made the backfiring worse. So now I have replaced the carb mounting...


It seems that you have a vaccuum leak around the intake or carb, Check all hoses for good connections. You can spray carb. and choke cleaner around the intake and carb whole it is running and if the engine rise and lowers. you have a leak

Change spark plugs and now car wont start.....1994 ford tarus


Do you have the "firing order" correct? In other words, is each spark plug wire going to the same cylinder it was on before you changed the plugs? If you have done nothing else but changed the plugs then this is the most likely problem.
If when you try to start the car it backfires through the exhaust or backfires through the intake. Then this " IS" the problem. Good luck.

What is the firing order for a 2006 ford tauras


Sir,
There are two firing order sequences for the FORD V-6. It depends on which engine you have. The first is 1-4-2-5-3-6. The second is 
1-4-2-3-5-6. The in-line six cylinder engines use: 1-5-3-6-2-4. You should look at the intake manifold to see which firing order your car uses. The firing order is normally stamped or embossed on the top of the intake manifold.
