Have a 2003 didge Durango starts fine. When it reaches 55 and 1.5 rpms it runs rough why would it do this? have changed the fuel pump and spark plugs with just a little change

SOURCE: 91 honda civic dx 1.5L quit running properly.

bro, check ur main relay. its under the dash. replace it, check also ur distributor(replace it). and also your ECU

Testimonial: "right answer but I received it much too late. I went to a mechanic and paid him to fix it."

SOURCE: 1999 SL1 running rough

Had a similar problem; started fine but lost power under acceleration and would stall. I changed the fuel sensor relay in the fuse box located on passenger side of interior fuse box. Ran fine after that.

SOURCE: it starts fine, runs 20-30 seconds, runs rough,

check the actual fuel line. Also is it fuel injection or carberator

SOURCE: rough idle. rpms drop. misfire.

try your coil packs they go over your sparks or do plugs first and see what happens do affordable first
