BodybyFisher Posted January 13, 2016 Report Share Posted January 13, 2016 I agree airmike, get the HG issue out of the way, so you know how to proceed. Hjb981, did you stick your nose in the tank and take a wiff?, mine had strong exhaust odor.

hjb981 Posted January 13, 2016 Author Report Share Posted January 13, 2016 I definitely smells in the tank. It is particularly noticable how different it is when compared side-by-side to new coolant. I suppose it could be exhaust I am smelling - it smells pretty bad. I still think that I can smell a bit of gasoline (although not as noticable this time - it varies), but of course it is hard to tell for 100 % sure, since it is a mix of different smells.

rockfangd Posted January 14, 2016 Report Share Posted January 14, 2016 It is likely exhaust you smell. And I can tell you from experience I passed several by product tests when my 96 was doing what you describe but it was still bad. My huge tip to you if you want to try it. Crush a few bars leak tabs, put them into the lower radiator hose. Run engine for a few weeks. If cold start misfire disappears you know what your problem is. If I added bars leak it would make my misfire and coolant consumption go away for a short bit but it would eventually come back after about 6 months or so. That tip is cheap and easy to do. Depending on the occurance of your mmisfire issue you may notice a difference in one day. Please do a search for my thread called COLD START MISFIRE IN THE General Discussion section. you will likely get some useful info. I just want to note I am not badmouthing the engines or trying to get you to dump a perfectly good vehicle. Trust me I have dealt with enough of these and that is why I fix them and stick with them. I bought a 97 last month and right off the bat threw 2k into having the engine swapped. I call that loyalty. I want to be very honest and dont want to see people waste time and money chasing their tail.

Cadillac Jim Posted January 14, 2016 Report Share Posted January 14, 2016 We have someone on another thread that has a bad FPR with moderate to advanced head gasket leakage and he has gas in the coolant. And, he has oil in the water. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.
