I have a 94 honda accord ex 4 cylinder v tech. A couple of months ago it began hesitating at start and running rough, sometimes to the point of dieing and having to be restarted. I consulted with the person who sold the car to me, and learned that it was still running with the original fuel filter after 150,000 some odd miles. (most other major maintenece had been atended to) I quickly ran out and replaced the filter and everything seemed all better. Well a couple weeks ago the car began having the same problems but worse than ever. The car will (sometimes) start only to get to about 1000 rpms and die. if i start and then give it about 50% throughtle i can usually get it up to about 3000rpms where it will run fairly well. if i hold it like this for several minutes i can then get it into drive without it dieing and drive off. but as i drive every time i stop and begin to accelerate it seems to take longer and longer to pick up speed untill the point where it shudders and misses and just goes along at a crawl untill it finnaly breaks through the ruff spot and makes it up into the 3000 rpm range. aside from that even before it gets to the point mentioned above when i give it gas it shudders and sometimes seems like it might die. the exaust smells verry rich and the only way to get around (when i absolutly must) is by warming it up and then just barely tapping the accelerator repeatidly to get up to speed. all vacuume hoses seem fine, all relavent fluids are good, voltage is good and spark plugs are clean. when the fuel line is pulled off the fuel rail and the key turned to on fuel sprays (liberally) for 2 seconds as i have read it should. Any advice would be greatly appreciated. I have started a new job that is 20 miles away and dont know how much longer i can bum rides.
