rickyrick562 Posted January 23, 2014 Report Share Posted January 23, 2014 So I was driving on the fwy and was trying to merge to the right but they wouldn't let me so I floored it to pass him and now the truck has a check engine light and it shakes when stopped. Also sounds like the exhaust cracked some where because when driving it into a parking lot it just sounded like the exhaust was leaking very bad and smells of gas. It still drives somewhat just shakes like crazy. Could it be the motor is shot. Truck has just under 75k miles Any ideas? Idk kinda fed up with this truck plus it's my daily and the semester just started. Now I'm car less. Might just buy a beater for a few hundred bucks until I either decide if I want to fix it or get rid of the ss. Idk just venting Quote Link to comment Share on other sites More sharing options...
CJ_978 Posted January 23, 2014 Report Share Posted January 23, 2014 check your spark plugs, and wires, if its not connected to coil back it will cause it the truck to shake like crazy very rough idel.. and not to long ago my #1 spark plug came loose and sounded like a bad exhaust leak, but it was actually a compression leak.. other then knowthing that from experience i dont know what else it could be.. hopefully you can get it fixed!

12'SROCK Posted January 23, 2014 Report Share Posted January 23, 2014 First off check why the MIL turned on. Inspect from the manifolds back to see if you see any visual cracks or anything. Also check what was mentioned above. Good luck! Quote Link to comment Share on other sites More sharing options...
rickyrick562 Posted January 23, 2014 Author Report Share Posted January 23, 2014 You guys think it safe to drive home 10miles or should i call AAA and have it towed Quote Link to comment Share on other sites More sharing options...
12'SROCK Posted January 23, 2014 Report Share Posted January 23, 2014 I wouldn't dive it until you rule out what's wrong with it. Quote Link to comment Share on other sites More sharing options...
BlueAWDSS Posted January 23, 2014 Report Share Posted January 23, 2014 My vote is you burned up a spark plug. Or one of your wires were touching the manifolds and burned through and shorted and then also burned through your manifolds.

rickyrick562 Posted January 23, 2014 Author Report Share Posted January 23, 2014 Which spark plugs should I get?i hear everyone likes NGK but which ones and how much should I gap them. I am supercharged if that makes a difference Quote Link to comment Share on other sites More sharing options...
CJ_978 Posted January 23, 2014 Report Share Posted January 23, 2014 (edited) I got ngk in mine, that's what was recommended, but I'm not SC.. Like above have it towed, and check your spark plugs and wires you will know if they are loose or not, or wire is off... If you start it up and let it idle look under the hood to see if you see the wire boots shaking like crazy or it arcing out off headers or something.. if you go to napa or something tell them the brand you want they have ngk i beleive and they are already pregapped almost all sparkplugs from places come pregapped Edited January 23, 2014 by CJ_978 (see edit history) Quote Link to comment Share on other sites More sharing options...
shawnss Posted January 23, 2014 Report Share Posted January 23, 2014 so does it idle rough or did you never let it idle long enough to know. did you check the oil pressure once it started acting up? was it puffing any smoke out of the exhaust that you could see?

rickyrick562 Posted January 23, 2014 Author Report Share Posted January 23, 2014 There is no visible smoke so hoping its just spark plugs. But yeah I drove it like 3 blocks and it was backfiring and just very rough idle. So gonna out new plugs this weekend. I have msd wires and they look fine. Which NGK plugs are you guys running Quote Link to comment Share on other sites More sharing options...
shawnss Posted January 23, 2014 Report Share Posted January 23, 2014 If you dont hear any knocking/ ticking noise then I'd look into plugs as well. do you have a code reader? watch your oil pressure just to make sure its not low. also does its backfire and spunter while idleing or only once the motor has a load on it? like once your trying to move it under its own power? I have dealt with my fair share of backfiring and missing. being my truck was turboed for many years. Most of the time it would idle pretty smooth and have no issues until I put a load on the motor. I'd normally just swap plugs and start there since plugs are cheap compared to most parts. how old are your current plugs did you gap them properly for boost when installed?

rickyrick562 Posted January 23, 2014 Author Report Share Posted January 23, 2014 Yeah only backfires under load. Don't have a code reader but do have access to one through my buddy. The dealer installed my last set of plugs so I'm assuming they gapped them to stock specs. What should I gap them at? Quote Link to comment Share on other sites More sharing options...

For boost they call for .028 - .032 factory is a lot wider like .045 - .055 or something like that I havent used stock gapping for along time but thats what I remember. I always ran mine at .032 with the boost level i was running 13lbs. anything higher than 15lbs I'd close the gap to .028 so the spark would get blowin out.

rickyrick562 Posted January 23, 2014 Author Report Share Posted January 23, 2014 Yeah the NGK say they come pregapped at 0.57. So are you running the iridium one? Sorry to ask so many questions just trying to get it right and thanks to everyone that has helped so far Quote Link to comment Share on other sites More sharing options...
shawnss Posted January 23, 2014 Report Share Posted January 23, 2014 (edited) No I never ran the iridium plug. I can't remember the plug number off hand. But I'll check the number when I get home. I do run NGK they are a tr something I can't quite remember. But I'll check. Edited January 23, 2014 by shawnss (see edit history) Quote Link to comment Share on other sites More sharing options...
