LT1 Diagnosis
Hey all. Got a 94 with 53000 miles. Recently, I’ve noticed that the cars acceleration and overall power is not what it usually is. The idle is rough currently, the car starts great cold but a little rough warm, only codes I have are the H41 code. When I step on the gas, the responsive really ain’t the best and feels very sluggish. I have a new optispark, plugs, wires. I changed over to an open air lid and k&n annd had to tighten a spark plug due to a ticking sound and then after that the problem started (ticking sound stopped). Figured I over oiled the filter so changed the maf sensor and got a traditional filter but issue is still there. What do I do?
