95 Chevy 6.5 Turbo Diesel rough idle - HELP
Hello all, rather new to the diesel world. But I've got a 1995 Chevy 6.5 Turbo Diesel with the PMD relocated and 40 lb marine injectors. Bought it with these mods done. Ever since I bought it it idles extremely rough (if it was a gas engine I would say it's misfiring or missing altogether). It's so rough that the entire motor shakes in the bay and you can feel it moving the whole truck while sitting in the cab. Runs and drives as I would expect it to, although the throttle is very touchy. There is no holding it at a certain rpm. It's either accelerating or decelerating. No check engine lights. Need help please! I don't have the money to just throw parts at it.
I posted a link to the video I recorded of it idling, you can see the engine shaking back and forth. Unfortunately the video hides some of the roughness in the sound quality... 1995 Chevy 6.5 TD rough idle: http://youtu.be/nWg3Ezc_9lk |

Have it scanned for trouble codes first but symptoms might be throttle peddle,IP or optical sensor electronic noise filter related-even a bad injector could contribute to the miss.
You could also google "paper clip trouble codes" and get them yourself and post the codes here for further assistance. |
