Whats up guys...so heres my story, a bit lengthy but any help would be GREATLY appreciated..
I have a 98 Sport with SOHC Engine..Recently maybe 4ish months ago I notice both a rattle when idling (which seems to come from cats and/or muffler etc) and also a strange tick/almost diesel like sound when accelerating around 1900-2100 rpm. So I figured that they might be related, I figured the noise might be coming from the cats at idle and under a load while accelerating..I go to an exhaust shop owned by family friend and have nice after market muffler put on (cats checked out fine but muffler was shot). Idling noise solved! BUT the noise at 1900-2100 rpm still exists. The guy at the exhaust shop suggested maybe trying Premium gas to see if the noise subsided...no help..This exhaust replacement was done 2 weeks ago - While the noise at 1900-2100 didn't really bother me too much NOW I have a noise/tick/rattle coming from the engine at idle and can be manipulated by barely touching the gas while in park (noise gets much more rapid). The mechanic at my work gave my truck a quick once over and suggested I maybe get an oil change although I wasnt due for one. Oil changed, still same noise. I am assuming these two (the rattle at idle and the rattle at 2100RPM) are related because at 2100RPM the noise seems more profound now. Work mechanic also stated the noise seemed to him (and myself) to be coming from underneath the engine towards the center. He also said that switching back and fourth from 87-93 octane wouldn't cause this noise. PLEASE HELP!! I love my ex but im getting tired of all this BS, I was so happy to solve the rattle with the muffler and now this...
EDIT: I also failed to mention..this tick/rattle when Idiling gets worse/more rapid when I turn on the A/C?
I know my stuff about car electronics and am decent when it comes to the mechanics but am no expert..but....Could this be the infamous cam chain issue? Could it be the connecting rods? Any other ideas? Does anyone else have this problem?
