Hi, so I took my car to a different mechanic last weekend. He found that the heat shield covering the exhaust output on the engine isnt tied down correctly and causing some random rattling especially when pulling away and gear changes. There is still ticking coming from the engine, he says the timing sounds right and it might be the lifters.
I have noticed 2 days ago that although the car sounds fine apart from the ticking and revs are fine. When I am driving and change into 3rd there is some hesitation.
Also when at idle 750 rpm the rev needle is constant, if increase the revs to 2k it stays constant. But when its at about 1300 rpm the needle fluctuates as if there is a misfire, it goes from 1300 drops to just above 1k and starts fluctuating. So when I am driving normally when I change to 3rd gear the car feels like it slows down and then slowly picks up acceleration.
If I drive my car hard with high rpm gear changes I dont feel the hesitation and sluggishness. But the ticking never goes away.
I have the obd2 tool in my car now but I think the misfire is too low for the ecu to throw an error code. Could the timing still be out by a little? Which is causing the ticking and misfire?
If you guys think it is the timing. I will have to get someone else to redo the timing and hope nothing got damage during the time ive been driving it and told it is fine.
