My 89 HF with 210,000 miles failed emissions because the hyrdocarbon level was too high. Especially at high idle. It did this before and the guy at the shop was able to tune it to get it to pass.
I moved to a new county and this new shop says it can not do anything.
What can I do? ATF in the pistons?
Thanks in advance.

Go out and get a can of SeaFoam. That stuff works miracles in the engine and helps with emission alot.
