    Will a 1990 zr1 run in full power mode with a check engine ligt on

    Hib the 90 does not have a mill code. My 91 at times sets one at times, pin pointed to egr vacume switching valve, and when i saw that the vacume switching valve to the egr was hard to find it got me thinking if something like that happened to the 90 and the part became unavailable what would be...

    Will a 1990 zr1 run in full power mode with a check engine ligt on

    I have heard a 1990 ZR1 will not run in full power mode if the check engine light is on. My question is if you happen to have one and the CEL is on is there any way to bypass this. The reason i ask is i have a L98 car and some parts that can set the CEL are not available any more.

    Is this normal M21 noise

    I am ok with doing the rebuild I am a mechanic at a toyota dealer. I have had no luck with finding different gear ratio's for the m21. If i rebuild my m21 I will replace the fist gear back to original 2.20, but was thinking i may be better off with a m20 for a more street friendly first gear...

    Is this normal M21 noise

    I priced out a rebuild kit for my m21 and including purchasing a first gear cog am looking close to 400. I will do the labor myself if i go that route.

    Is this normal M21 noise

    I think the whine may be a little excessive. I also am not crazy over the first gear ratio of 2.20. So realy dont know if i should rebuid it and replace first gear. Have considered swaping to a m 20 for the better first gear ratio, or doing the 5 speed swap. If anyone has done any of these...

    Is this normal M21 noise

    My 74 has a M21. Trans shifts normal, but in first gear when i accelerate i get a whine noise, only in first. Is this normal. Is first gear a straight cut gear which is making the whine or is this a sign of a problem. Thankyou.

    1981 Corvette ECM vs engine mods

    This may not be correct but i am sure someone has input on this thought. If you have a 81 and want more power and a lot of states do not require a check engine light function for emissions inspection on such an older car could you not bypass the engine ecu with a carb and distributer change and...

    I just purchased a 1974 convertible 4 speed car. My problem is that it only has lap belts and i would much prefer a 3 point seat belt with retractable shoulder harness.

    Help! engine not raising idle when turning aircon on

    Hib i dont know if this is correct and applies to chevy, but on toyota if the idle starts droping real low you can dissconect the battery and clean buildup on the throttle body to restore proper idle level. I have heard that on some cars you can not clean the throttle body for risk of removing...
