    1994 2.4l pickup/hilux all standard options manual
    250kmiles
    My issues is acceleration is Honorable off the start (low rpm) it seems to acc fine if you push petal just a little, if you push hard just bogs. if you get up in rpms it does seem not to have to much lag but definitely not running right. always kills at a light as you roll up unless on the gas.. Cold start ups it will idle somewhat...

    Repairs to try to fix issue (100miles or less):
    new fuel pump in tank sock too
    fuel filter
    all new injectors
    new mass air flow sensor
    new spark plugs
    distributor & rotor
    I have sprayed brake cleaner on all hoses and doesn't seem to have an air leak
    Also had and exhaust guy tell me he didn't think it was the catalytic converter it is only 3 years oil exhaust is in ok shape...
    Did compression check all 4 holes 135psi
    also I run mobile 1 always and change regularly


    older repairs:
    new clutch
    flywheel
    brakes and rotors


    Please help me out can't seem to fix the issue? Tomorrow I am going to buy a new ignition coil, but at this point I am $800 in and have not fixed and want to sell this truck for 2-3k if possible so I am just pissing money away at this point.. This has been my truck for 10 years with no issues this bad...


    Thanks

    Im with jetas, possible vacuum leak, did you also spray the under side of the intake?? If not my second guess is that your timing guides have broken and your off time. Have they ever been replaced in this truck??

    Timing guides don't even know where they are.. That seems very likely.. I started one day and this is how it has been sense..

    So are you saying the timing chain skipped one tooth... Can I advance the timing to see if it comes back to life...

    Don't have a smoker but cigar may work too.. I really think this skip one tooth on timing chain maybe the issue.. I am going to advance the timing tomorrow to see if it gets any better.. But tell me if I am right if it skipped one the timing lines aren't right anymore right.. Just go off sound and how it runs at that point.. Because I am just trying to sell this thing don't need to get into a 1k repair to change chain an guides..

    Yes, loosen that one bolt on the distributor. Move it back and forth and just see what it dose. All it will do is kill the motor once you have gone to far. I've seen chains guides fail
    And skip 2 teeth before.
    This is kinda a half ass method but it will give you a give you a ball park idea.
    Again Vacuum leak based off symtoms is still very high on the list.
    Try buying a few cans of the cheap carb cleaner for your local parts store. Rev engine to about 1k and just spray the stuff every where! Under the intake as theirs a few hoses you can't see and also the back side of the engine and just listen for the abnormalities in the engine running

    You could have skipped timing and those lines will still be perfect... a bit deceiving I know.

    i would still check the timing guides, it's fairly simple to do. take off valve cover and look down timing cover with a flashlight. it'll still run but there's a fairly distinct rattle sound the engine makes too, especially at low rpms like when you first start it up or when you start to accelerate. if you timing went off all of a sudden i would be suspicious of the cause. at 250k if it's the original timing set it's very possible.

    some trucks make it further on the original set, some less. my 1993 went around 180k before it broke the guides on me while i was doing donuts in the mud. my dad's 1986 pickup went 350k on just oil changes and one clutch replacement, original timing set...then he bought a new truck and a week later the Toyota got jealous and left him stranded with a rod blown out the side of the block. my uncle still drives that truck 17 years later (after an engine swap of course)

    good luck with the sale, i'd at least let the new owner know about this recent hiccup.

    cool man glad you fixed it. $50 bucks would be nice but as a TOYOTA minis community member that's not what it about! I retired from TOYOTA 3years ago Just glad that I could help.
    Rebuilding the engine is fairly low cost however that's contingent you are doing the labor your self. Hopefully you get many more years of use out of your pickup!

    That's reasonable. Post to your local Craig's list and offer up and I'm sure you will have it sold in no time at all.
