Older head gasket sealants were very bad about clogging thermostats, water jackets, etc. I spent a while extensively researching results from different sealant products. Based off the severity of my head gasket leak it was minor compared to leaks other people had been able to solve using head...
Yeah my conclusion was it is just leaking strictly into the cylinder. Judging by how much coolant I am losing my thought is it is a fairly small leak. The effects I am seeing from it is sometimes causing a cylinder misfire at idle, as well as a slight decrease in mpg. So for now I am going to...
Also I made sure to check the throttle body for the issue of not closing all the way as I had seen it before on another thread. It closes completely so the issue is not there. I also checked for vacuum leaks using brake cleaner, and there were no vacuum leaks causing the idle to fluctuate. The...
Yes when this problem initially began I noticed on cold start I have vapor coming out of the exhaust pipe, also the engine began losing coolant but not on the ground below.
Yeah I am under the impression the high idle is from the computer having not learned the new IAC. I will try out spraying carb cleaner and see if I can figure it out.
Thanks for the information on checking the coils, I gave a new IAC a try and now the problem is still there but not as noticeable as the thing is idling at 1500 rpm. And while I was in there I cleaned the MAF sensor and checked vacuum lines and the throttle body fly, everything looks to be ok. I...
Running into an issue recently of my 4runner misfiring at idle. A couple months ago it developed an issue where on cold starts after a night of sitting it would fire up and run rough for about ten seconds then it would go away and be ok. Then recently it is still doing it on cold start, but now...
