    Hello everyone I’m new to this thread I just got a 1998 limited 4 runner it’s got 108k with a supercharger on the way. And much more to come.

    So I’m experiencing a stutter when it’s in park and when I slightly rev the motor it got a hesitation/stutter I changed spark plugs, spark plug wires, coil packs, and I cleaned the maf and the throttle body also iac valve. Still the same issue.

    LEDs all around, otherwise bone stock.
    Sounds like you did all the right things. I was going to suggest TB & MAF, but you got it. It must be a deeper issue. Linkage? Spark plug gap? Fuel filter? Only things I can think of.

    ^ what he said, check spark plug gap. Wouldn't hurt to check compression on the cylinders either, check air filter.
    Did you get new injectors with the SC or reusing old ones?
    How old is the gas?
    20 year old vehicle with 100k on it, that's 5k miles a year.. it needs to be driven.

    I didn’t check any of the fuel components yet the person I got it from ran a oiled intake he over oiled it like crazy and made a sticky mess i cleaned all that up as much as I could I didn’t check the spark plug gaps they’re supposed already be gapped when you buy them. So I didn’t check it I’ll check it when I get the chance
