Here is the pisser, I have had the cruiser for 2 years now running fine, no codes. I smell gas every day, after about 7 days, and laying on the motor, standing on my head on the motor, finally located the fuel leak, the infamous fuel pulsating damper!
So, I replace it, and the fuel pressure regulator because I had a new one for just in case it went bad, I have 235,000+ miles, on my '88 3FE. I was getting no codes when the fuel damper was spewing fuel. I fix it, replace the FPR, and mention to the wife I have to smog the truck for the registration, yeah California.
The very next day on the way to the smog check the check engine light comes on!!! What tha.....?
Check the codes and get 25, 26, 71. I'm scratching my head how can it be running to rich and to lean?
For code 71, I research it on this forum, clean the EGR air temp sensor (California only model) thx again CA!! Cleaning the sensor didn't help, still getting the 71.
So, I'm still getting all three codes!! The motor runs fine, seems to get around 14mpg, and accelerates like most 2FE's faster then an old VW diesel pick up but slower then a VW bug. Motor starts right up, has no missing, tho the idle once warm seems to be a little rough, but it does have 232,000 miles, and most likely needs a valve adjustment.
My problem is all of the parts are $$$, and thanks to Toyota we get two O2 sensors $110 ea, two cats at $220 ea in CA or $90 ea 49 States, and one EGR Temp sensor $115 in CA, none for the other 49 States.
So, I want to get the right one causing the problems. I would like to know what part usually gives code 25 and 26 at the same time? I can check the voltage on the O2 sensors to see if they are bad and will do this weekend.
I'm just looking for best things to check first to help save time under the hood! I only get Saturday and Sunday to work on vehicles, smog is over due, and have to put vintage air A/C in the wife's car '69 Datsun 510 with KA24DE, no SMOG on her car!!
So would love to here from whom ever has some good smog and code debugging skills. Thx
