I believe spd-dmn just did this stuff on his own car recently he is likely willing to help you out.
do you have an aftermarket or stock exhaust on the car? I get a discount at the local NAPA I should be able to get you a decent price on it and we’ll get that thing to pass the legal way for a lot cheaper than you were quoted.
It doesn’t need a cat. EGR BPT is not working by the NOx reading. The vac line gets hard and cracks causing the EGR not to work. With the weather change pre test warm up changed to 30sec not enough for and older cat to warm up. Shops/techs know this but they they tend to make more money when they fail.
Thanks for all the helpful replies and advice, but I just have a quick question: Is it bad for the car mechanically if I don’t get the problem fixed, or is it just more of an evironmental issue? If it actually decreases the performance of my car, I should probably just get it done right and do a re-test. Any opinions??
I agree your timing might be off causing excessive hc and nox but that would be in the low hundreds not thousands… your egr is likely malfunctioning, which can lead to mild pre-ignition at light throttle or at the least retarded timing… which makes even more nox and makes your cruising fuel economy garbage
O_O!!! E-test shit on an s13/driftcars pointless Im pretty sure 90% of the members on the board have no cat and 3 - 4 inch piping along with fake Etests.
I dont know about that. They are forced to charge 35 dollars by the government so after 20-30 min on the sniffer I doubt they are making anything that is worthwhile to them. They’d rather do an 800 dollar brake job in that time to really rape your wallet.
Funny thing is I buy a sports car pay the extra insurance and buy the 94 oct gas and the goverment says run a cat. I say fuck that just pay 200 for a fake e-test;)
