2003 ssei problems
Had a Jasper manufactured engine installed after a major problem as a result of coolant leak. Researched installers in south jersey, used a location with the best reviews. After two weeks got the car back, very sloppy work, wiring harnesses not routed properly, heat shield not properly secured, plug wire 3 on exhaust manifold.egr valve code. Plus more. Problem is car never threw a code, now I'm seeing Po 303 misfire on 3 ,po137, low voltage bank 1 sensor 2,car breaks up on hard acceleration, really pissing me off. Had transmission services, filter and new fluid, changed plug 3, and plug 3 wire,new egr valve. Not sure what to do next.Car is in great shape,love the car hate the problems that I see as a result of a poor install. Any suggestions?
