This is I understand the first year for heat risers. The truck runs great in warm to hot weather but complains terribly in even slightly cool weather. Below 50 degrees it has trouble warming up and below 40 barely can be driven as it acts like it is starved for fuel even with choke pulled out. The heat riser is in open position so it should be heating the intake. Any ideas? Thanks a million!

Maybe it's put together wrong or the plate has spun on the shaft. | | | | | Joined: May 2009 Posts: 15 New Guy | | New Guy Joined: May 2009 Posts: 15 | Thankx alot for the advise gotgasd! also was advised the heat chamber around the intake may be cloged with carbon not allowing exhaust to flow through and heat the intake ports. if thats the case i guess i'll have to disassemble. Thanks again. i'll try your advise first. Much easier fix. | | |
