I just changed the intake gasket set on a 1999 Honda Accord EX, the motor is a 2.3L4 I also replaced the sparkplug wires & sparkplugs with what it called for which is NGK & gapped them at.044. I changed vavle cover gasket, oil, & also added antifreeze. When I cranked it up it ran at about 900rpm & when you press the gas slowly it idles up to about 2000rpm & then bogs down & shuts off. So I went ahead & replaced the egr valve & it still does the same thing. I took the spark plugs out & checked them & they was a smutty black color on them. This is the second set of spark plugs that look like that. I undone the exaust pipe from the manifold & dropped it down thinking the converter was clogged up because it popped up a code saying the converter was effienency & then a undenified code which was P1259 before I even worked on it & it still does the same thing. Before I dropped the exhaust down, it had no pressure coming out the exhaust & was sucking in air more than blowing it out the exhaust. It has two o2sensors on it, 1 at the exhaust manifold & 1 on the converter. I dont know what is wrong. Is it possible it jumped time, it looks like the stock timing belt on it. Please help.
have the same problem?
