Ok, so I did a compression test and leak down test and everything turned out fine. Replaced fuel filter, Cleaned IACV, gutted the cat (just in case it was clogged lol the honeycomb structure on the inside was coming apart) Ive pretty much done everything possible that it could be minor wise.. Now im beginning to think its the fuel injectors or ECU or something of that nature. Everytime I drive it and hold it at 60 mph or hold the rpms at 3,000+ rpms, It starts sounding like its misfiring really bad and bogs down, it only does it under load at 3,000 rpms and above. The CEL codes say that its misfiring on Cyl 1,2,3,4 and it will give the multiple misfire on all cylinders code. I took it to a shop and they tinkered with it and said the injectors are working.. But I am thinking that they might be clogged maybe? I am getting frustrated because I take it to a shop and tell them what I think it may be and they replace all of the crap ive already replaced and charge me for it and wont listen to me, I guess because I am a female and I don't know what I am talking about.. I am just tired of dumping money into not really sure of what the problem is, I know I can take a chance and send my injectors off to get cleaned but theres that chance of them not being clogged and wasting money that I could've put the money towards fixing the problem. Sorry I know I sound hardheaded and I know Im always gonna have to put money into it, I just wish I could find the problem and fix it so I can get the emissions passed and I can drive it again.
