I gota 92 ES DOHC.130000 miles.It has an all asudden misfire. When the cars is idling it will misfire like every 5 to 10 seconds or so. Its not consistant. I changed my timing belt like 6 months ago. I checked my timing marks a couple days ago and and the marks all lined to where they need to be. I replaced the plugs and wires and it still runs the same. Im getn some used coils of ebay to try and test if that works. My computer was just rebuilt. It doesnt make sense to me. Its getn spark on all 6 cylinders. My mechanic at my work said it may possiblie be one of the injectors worn and is dripping everyonce in a while. But it would cost too much to get them cleaned or get new ones. I dont want to spend that kind of money unless im surethats it.Im trying to sell this car by the end of summer so I dont want to spend too much more money into it. I wanna get a vr4 or rttt. Any ideas on what the misfire could be. I also feel like it has lost alittle power compared to when I bought it like 20000 miles ago which makes sense because of more wear on the motor but but it doesnt feel the same. Also I use 93 octane gas just incase anyone of u ask.
