Hello,
I've tried five times to get my '89 TTA pass emissions on a stock chip. The only problem is HC, last test of (1.41) is just alittle bit too high compare to the first test (.92). The standard is (.80). The OC and gas cap test are ok.
I have added a 3" Terry Houston downpipe w/cat, 6 new spark plugs, new plug wires, 6 new injectors, oil change, new oil filter, and a new O2 sensor.
BTW the place that changed the injectors charged me $800 for 6 new factory injectors. Was I overcharged?
Would a smog chip help at all? Any suggestions or help would be greatly appreciated.
Thanx!
