Ok I found the post about what the different codes mean and I searched to find exactly how to read them, but didnt find anything. So can anyone explain to me how I go about counting the flashes to make sure I come up with , the correct codes for my car? If not, maybe you can tell me what is wrong.
I have an 88LX,carb, manual, new tuneup, new O2 sensor, and when I start the car it idles around 2k rpm, after 10 mins or so of driving, it will idles down to about 600 rpm or so and run rougher than crap. It isnt overheating [new tstat, water pump, rad, hoses, temp sensor and fan sensor] that I can tell and it runs great, just crappy when you are sitting at a light and have to keep your foot on the gas to keep the car running.
I am getting horrid mileage, probably not more than 20 mpg. Another thing I noticed this morning ont he way to work was one of my belts squealing when I first started up the car. Then when I got here it was idling like crap, but when I turned the headlights off it started running better all of the sudden.
Could it possibly be my alternator about to lock up, because that would explain the car idling down when I put the brakes on, because of the brake light coming on.
I talked to a friend who is a manager at a pop in mechanic place (express lube), he said whatever I do dont jack with the vacuum hoses. There are over 80 of them underneath the hood, from what he says.
I dunno if it is a vacuum problem or not, but I know I have got to get it fixed asap. I drive 120 miles round trip to work every day and this thing is eating me alive in gas right now. I spend between $70 and $80 every week, filling up every 2 days after only 240 to 250 miles.
:(
Yeah that is kinda what I am leaning towards also. It kinda sounds like I have an exhaust leak sometimes anyways so...
How do I go about testing for an exact vacuum leak or do I just visually check all of the hoses etc??
Yeah if it isnt too much trouble I might try to get that done this weekend, the intake gasket that is. Like I said, it was running a little rough, so I swapped a new O2 sensor on and it ran great for a couple of days then started running worse than befroe.
OK finally got it figured out over the weekend.
I took off the air cleaner and found a broken vacuum line, the after looking a little closer I found another busted line on the back of the carb. After replacing these 2 lines, I had to reset the timing as it was prolly around 10 degrees off or so.
The car runs much better now than it did before, but I still am not getting prolly more than 20 - 25 mpg.
Anybody got any more ideas what could be causing this??
:uh: OOPS LOL
