    How do I adjust air fuel mixture on 1986 Toyota Cressida straight 6 cylinder dohc

    Unless your engine has a carburetor, you can't adjust your fuel mixture. That is done by your cars computer. It analyzes your exhaust emissions and adjusts your fuel/air ratio.
    Your oxygen sensor(s) may need to be replaced, or there may be a computer glitch causing the problem.

    92 toyota pu surges in high gear

    High gear strains the engine more than others, so any tune up item could cause this. Leaking vacuum line, bad air flow sensor, clogged converter or muffler, weak fuel pump or dirty fuel filter all can cause this. I have also seen rust in fuel tank go right through filters and make metallic deposits on spark plugs which will then miss at high speed first and soon at all speeds. Try pulling plugs and "reading" them first. Then test fuel pressure while running at high RPMS.

    I have a 1991 Corolla FX-GT (AE92). On cold start the engine idles at about 2 - 2.4 krpm. When warm it idles just under 2 krpm. The radiator fan also runs continuously (I understand that this should only...

    First of all you have to check emissions, if you have smoke of some sort being emitted then it suggests an incomplete combustion is taking place.
    To solve this first you would need to install an ignition booster ( ~250$)
    and about the idling its normal for 4age to idle around 2k rpm but If you want to control the idling speed then you can tighten the screw just at the T.V.I.S (intake manifold) at the top right hand side of the unit.
    To get better idle speeds you may want to run synthetic engine oil instead of mineral oil due to the viscosity remaining somewhat same (at room and hot temperatures) with synthetic oils.
    finally have your A.F.M (Air Flow Meter) or M.A.P(Manifold Absolute Pressure) sensor checked and then finally get the computer tuned at a dyno facility through your mechanic and for the computer to be programmed for higher fuel efficiency.
    If you want to go further however have copper spark plugs installed.
    I own an AE92 FXGT. Its a sweet ride however mine is the 1988 corolla.

    Bring it to Auto zone parts store to check if any trouble codes are present they will hook up a scanner for free, the code if present will point you in the right direction if no codes are present the car most likely needs a tune up, when these vehicles get older the fuel injectors become less efficient and need professional cleaning, O2 sensors should be changed every 60 to 80,000 miles whether the check engine light is on or not.
