About 2 weeks ago my hose that goes to the upper intake from the front to the charcoal canister had a leak,and my car felt like it was missing and so forth. I replaced it but then my family mechanic(my moms cousin)turned my timing after he was done replacing my hose,i got mad at him and told him wtf are you doing.He doesn't have a timing light either. Well since then when i start my car when it's cold,my needle jumps up higher than normal and kinda surges for 2 secs and then it idles properly. I triied fixing the idle screw but i get that same thing. Also theres about 4 hoses in total that are joined by some plastic joiner pipe in between the rubber hoses that go fron the intake to the charcoal canister.They do all look old,i was wondering if i should just replace them all too. I'm worried that he turned my timing up and cause sometimes i can smell the gas from my car a bit,i had it at 14,but i haven't had time to go to my speed shop to get it checked out.
