I already passed the smog previously by replacing o2 sensor and cat from the previous 2 years ago. Now I need a new smog check and ran into these issue and need help again.
there isn't any coolant leaking so I thought I don't have to replace unless it is leaking? this should be done every 100k miles and I am only at 170k miles.
I haven't changed the spark plugs or wires. I think I brought the car used at around 135k miles and I am on 170k miles now. I haven't preformed a piston soak yet either. What would be the cost estimate from a mechanic for these things? a 95 Accord isn't worth much and the repairs might be more...
I need help again as my smog is due. I did the following before the smog test. Drove highway for 1 week to burn up build up, changed oil and filter, used Techron gas with Techron concentrate. Drove for 30 mins so cat was hot enough. I ended failing.
Readings are:
RPM 1857 15 mph car measured HC...
I added 3 gal of e85 into a 1/4 tank. the 1/4 tank already had 87 gas in it. I added another tank of 87 gas. My ratio was 1:1 for each gas, 87 gas, and e85. After this, I was around half full. My gas tank maxes at 17 gallons.
I already had 87 gas around 3 gallons existing and added in 1 gallon of 87 to mix with 3 gallons of e-85. This would equal a 1:1 ratio, but I don't know why the NO went crazy.
