Mine runs fine until it gets warm usually 20 30 min of freeway, then when put in reverse or pulling into parking spot, drops to very low idle and sounds like the loudest diesl motor, hit throttl to up idle and back to normal. Have found no one that can tell me where to begin. no engine lights
Idels very rough ...Bought it NEW. Have maintained very regular...Replaced original IAC...No improvement...My mechanic is at a dead end.....Have not cleaned throttle body as yet. I am thinking it may be the TPS ($42.00)....Need your advice....
Rough idle when sitting and diesel sound coming from engine. Shops will sell you on a cam timing phaser replacement at about $1800. All you need to do is: CLEAN YOUR THROTTLE BODY for the rough idle. REPLACE THE VARIABLE CAM TIMING SOLENOIDS to quiet the diesel rattle. If you do it yourself, it costs $120 for both (buy the solenoids off ebay) including a $10 bottle of throttle body cleaner. Go to youtube and search what I have given you and there are numerous videos. I was ready to drive my truck off a cliff until I took the advice I am now giving. It works. CHANGE YOUR AIR FILTER REGULARLY to prevent the rapid throttle body gum-up. You are welcome!
I had a problem with losing antifreeze,found code po307 and changed out intake manifold with an aftermarket one and the injector on cylinder 7 and put a new set of plugs as I started it the converter on the left started to get cherry red with engine idleing its rough idle and has power what do you think would be the cause
