Just took my 88 Camry with 2.0L 136k miles to local emissions testing & it failed on the HC (hydrocarbon) reading. I had an HC reading of 1380 & the limit is 220.
The history on the car is that it was parked for 3 years & so far I've replaced the fuel pump, filter, injectors, air filter, muffler & battery.
The engine idles fine in park or neutral once it warms up but has a rough low idle when the engine is cold or while in gear (automatic) & has stalled out a couple times while in traffic while at a red light. I've seen several remedies online as to using seafoam or another type of cleaner to flush things out etc. The tech at the emissions testing center suggested that it could be bad vacuum hoses due to the age of the vehicle & deterioration, also recommended was advancing the timing.
