    Downstream O2 sensors

    Thanks to all. Was just curious. Was able to pass smog barely with a fuel injector flush (? poor fuel atomization). Will keep the rear O2's for now as cats are new and should be working well.

    I liked Poterfield R4S for low dust and squeal

    Downstream O2 sensors

    1997 39,000 miles. Makes since they can go bad. My question is, do they have any effect on air/fuel ratio? Or only throw a CEL when cat not functioning.

    Long term adaptive high?

    Ok. I think I got it solved. Went to Dealership and they recommended flushing the fuel injectors and replacing the REAR O2 sensors. Did the first but not the second. Rechecked smog today (first shop I went to wouldn't do Vipers..too complicated?!?) and PASSED! After front O2 and new high flow...

    Downstream O2 sensors

    Having trouble passing smog. New cats and front O2 sensors. No check engine light. Dealership mechanic says rear O2 sensors are reading funny and to replace them as this can effect mixture. I thought the rear O2s were for monitoring the cats only. Is there any point in changing them with no...

    Downstream O2 Sensors

    Having trouble with smog and it seems one bank is running rich. Took it to the dealership and they flushed the injectors and told me the rear O2 sensors were reading funny. Said I should replace them as this could be part of the problem. My understanding is the rear O2 sensors were only to...

    Long term adaptive high?

    I think what was concerning was the difference in the adaptive between banks, 10.5% left and the right 0.8% and the fact the smog check suggested it is running to rich. Still wondering about the rear O2 sensors. They are not expensive but don't want to replace them if they have absolutely...

    Long term adaptive high?

    OK. Might be making some progress. Brought her to the local Viper tech. He confirmed the adaptive high on the left 11%. He flushed the fuel injectors and the adaptive dropped to 5-7%. Right side is still less but he feels this is significant. He also recommended changing the downstream O2...

    Long term adaptive high?

    Update. Replaced O2 sensors and no change. I think I am going to take it to the dealership and see if they can solve it. Will check grounds first.

    Motive Pressure Bleeder or Speed Bleeders?

    I have used the Motive system numerous times to bleed my Gen II and it works very well and is simple. No running back and forth to pump the pedal. Ford 3 prong cap works great. Shop manual recommends pressure bleeding. I have heard that bleeding by pumping the pedal can result in over travel of...

    Long term adaptive high?

    Thanks! I appreciate all the input. I took it to a mechanic friend who works on European cars. His scanner showed voltages of about .2 for both O2s at idle with brief boost to .85-.9 with reving the engine. I will see if his scanner can do a graph (Snapon scanner) Emissions were: 15 mph 38HC...

    Long term adaptive high?

    I recently failed CA smog. Passed at the 15mph test but failed at 25 with high HC and CO, very low NO. I foolishly thought it was the cats and replaced them (Random Tech ceramics) with no change in emissions. Car runs well with no codes. Ran a scan on it today. O2 sensors cycle from .2 to .95...

    Headlights photoshops

    Totally agree about the LED's. Will be as out of style in 5 years as the gold trim Lexus used to use. At least they look better than the Audi, Mercedes, Chrysler leds.

    Viper headlights come straight from the Koenigsegg Agera

    Wish they would ditch the LED's. They are going to be as out of style in 5 years as the gold trim on a Lexus.

    Shift rpm

    Have only hit the skip shift once in 12 years. It is a non issue the way I shift.

    Pro's and Con's of billet under drive pulleys for Gen 2?

    "Would a cooler thrmostat counteract the negative effects of underdrive pulleys?" No. Thermostats only determine the lowest temperature of a warm engine but do nothing to effect the high point.

    Tranny ..I was wishing for F1 Paddel Style Shifter

    I'm all for an automatic paddle shifter it if it is a 30,000$ option and only available in pink so we clearly know who can't drive stick..... :smirk:

    Tranny ..I was wishing for F1 Paddel Style Shifter

    "This is like telling a Formula 1 driver that they are less talented because they are not rowing the gears" Of course it takes less talent to drive an automatic that a manual! Even the F1 drives know this. The lack of an automatic transmission (paddle or otherwise) and the V10 are two things...

    Absolutely LOVE this shot!

    Only thing I don't like are the leds around the headlights. They are going to be as out of style in 5 years as the gold trim Lexus used to use on their cars.

    Scariest exprience in a car ever!!!

    Agree. Sounds like an accidental 2-1 shift. Did this on the track once and it was instant spin till I hit the clutch again.
