Low idle and running rich

SleepysSupra · 01-13-2008, 11:37 PM

Well if the blown head gasket is filling the cylinders with antifreeze that could cause it to stall out too. I just did the head gasket on my 88 7MGTE and it wasn't hissing, thats more likely a vaccume leak, but if the car sat for a while the antifreeze would seep into the oil pan and it would run fine for a while but after running for a while it would start runnning rough and then die out. At ope throttle it would run fine because the engine was exhausting the antifreeze faster than it was drawn in. If your leak isn't a very big leak then that could very well be the case. Mine on the other hand, I put a new head gasket on mine and never had the head checked. My mistake, I had to do it twice and have the head machine at a local shop here because after checking my head I foud it was warped. The machine shop had to take two thousanths of an inch off mine to fix it. Well let me know what you find.
