Hey all,
Been a while since I've posted. Happy New Year, and Merry belated Christmas!!!
If some people would read this and reply if you have suggestions, that WOULD BE AWESOME!!! But please read before, because I have done work and I don't wanna read suggestions I've already tried/done.
So a while back, like late 2011-2012, I was getting crappy mpg; usually I could get 16-18 city, 18-20 combined and 20+ for highway, usually 20-23 mpg. I really liked that and considered it nice mpg for a mid-size SUV. So it was getting noticeably different mpg and was smelling gas upon start-up, and it was a little hard starting. Didn't really run rough or idle rough. The dealership at the time replaced the fuel pressure regulator as it was leaking really bad. So the mph improved for a little bit but then went down.
I had a tune-up done last year and haven't yet gotten to the point where I need another one. They replaced the fuel pressure regulator last year in January, as they smelt gasoline on the vacuum hose. I just did a whole bunch of work to try and solve what still might be a fuel leak/bad mpg problem...
That work included doing my temp sensor/thermostat, as my engine has been running cool since July of 2012, cool enough to warrant replacing it. I heard that if the engine runs cool then the computer will feed more fuel to the fuel injectors and therefore runs rich...so I did some fuel injector cleaner because of this and also because they hadn't been cleaned in a while...we did my fuel vent because a trusted mechanic said those can get clogged up...mine wasn't too bad but still a little clogged nonetheless. Also did the charcoal canister and when we took it off it was saturated with gasoline. Replaced the air filter, too. And cleaned the throttle body. That's pretty much it for the mpg related stuff...we also did power steering pump, master cylinder, passenger side front hub (did the driver side last fall, it was making a lot of noise...replaced this one as it was getting kinda old and bad, too), oil pressure sending unit...:crazy::crazy:
So I know that obviously the fuel injector cleaner will take a while to clean (I've heard anywhere from one tank to a few times) and I'm going to track my mileage. When I started my car yesterday and this morning, however, I noticed again, as I have been noticing for a while still, there is a strong smell of gas. I noticed it right outside of the driver door (don't know if that helps), as I didn't notice it inside the car. I had forgotten to unplug the cord for the block heater and stepped back out after starting it up. It was definitely gas and I know that it's not really normal to be smelling that. I noticed my mileage is still kinda where it was before, getting like 12-15 city/combined and only as high as 17-18 mpg highway. Like I said, I know that the injector cleaner will take a little while to clean. Before it seemed like my acceleration was sluggish and had to really kick it down to get going, especially uphill. Everything seems ok now, it seems to run great...only thing is the gas smell and the mpg, which I think the mpg will be improving with the cleaner unless there is still a bad leak.
What do you think? Where else would have I have to look? I know I've read about looking at the rail, but as far as I know, we didn't see any gas. I don't think it would be leaking fuel injectors just because it seems to run fine...but I could be wrong.
Any advice would be nice, as I love higher mpg and I don't know where else to look or what else to do :bonk::bonk::bonk::thx:thx
