Hi, for about a week now when starting ("cold") it starts cranking and sometimes (almost everytime) i hear like a BIG...... "explosion". Ok the sound is like a "pop" but a damn big pop and im scared it will be the starter, i can get a video with sound, but since it happens 70% of the time i could not be sure to get it, also it started after i "tightened" the alternator/ac belt tensioner, but a friend of mine said that is not the problem since it does not give anymore problems than that.


BTW: when i said cold is what could you expect of a first start but at 87-97 Fahrenheit

I've heard about this before, I think it's an intake backfire. Do a search.

agreed. as ****ty as it sounds... a 'burp' through the intake almost always indicates a timing problem.

not really if you know how to work on an engine and have worked on them for a while.

Does it start rough?

Luisjo

well... when it does the "pop" i starts at the 2nd try, otherwise the 1st

Luisjo

if it was the timing chain id expect it to run rough, check fuel pressure, spark plugs?
