well, for those of you who have followed my previous threads I had bogging and power issues and then thought it was a bad wiring harness. Well, I fixed the harness by getting lucky and taping a spot on the harness that looked bad and fixed it in about half an hour! well, now its back to its same old self, which means its running rich as ever, bogging at low rpm's, terrible gas mileage and little power. I know tis rich because of the exaust, its as black as a chiminey with carbon or whatever that black stuff is all over the inside, and I jsut wiped it clean (yes the inside) with a rag last week to make sure I wasn't imagining things. It has been doing this for a long time now(4k+), but I thought I could fix it. Well, new IAT, IAC, vacuum lines, and a good bit of money later its still not happy. But heres what is really messed up: when coming back from Georiga not too long ago after about 3 hours into the 7 hr trip, it ran perfect. Got near 30mpg (compared to 21-24) at 75, had tons of power and was happy to be alive. It ran awesome the rest of that trip. Hasn't done it since. After that, it was back to the same the day after, no power etc.... No chk engine light, secondaries open fine what is causing this?!@#$% I've gotta road trip 2k back home starting this thursday, and want to get better gas mileage then a truck! If it helps, I can back up about 6 months before this started, 28-30 mph highway was no problem, then it just dropped, not all at once but over a month or 2, and has never been the same since. I have been in 2 accidents, although you can only count one cause one the hood flew up and the other was a break in. After the hood flew up is when it started bogging when you first start it up(like hardly go forward if you floor it kind of bogging), but it has had power issues and bogging (although not as bad as when its cold) prior to that. Not sure if the body shop did that or not as I cleaned the UIM/LIM with carb cleaner instead of intake cleaner (if that makes a difference, not sure) the day I got it back from the shop. Any ideas? I want to sell it but can't afford a decent car, and it has 53k on it!!!! Any help before I drive it into the lake would be appreciated. Thanks!
