I have a crazy problem with 2001 Grand Vitara 2.5 v6 4x4.
I recently had timing chains, gears, etc replaced. 4 different mechanics verified the work, so I KNOW it is timed properly. This was done 500 miles ago. about 200 miles ago, new problem showed up.
Vehicle starts easy, BUT, has very strong fuel odor and fuel smoke. a few revs and its gone. Vehicle has crazy power and can easily do a 2 wheel burn out.
After about 5-10 miles of driving, things get strange. Put vehicle under ANY load or acceleration and I get a horrible spark knock and a cloud of fuel smoke. Throw it into neutral and rev a few time and problem is temporarily fixed....
Air filter is clean, oil is fresh, new spark plugs, replaced all coils, air intake sensor is new, replaced all vacuum hoses,
I run high octane , NO ethanol fuel...
Have scanned and there are NO check engine codes
Engine compression is good, Engine Temp is good,
I love this vehicle but it is wearing me out....
ANY IDEAS???
