    Hi guys. New v6, auto, 4x4, 1998 Tacoma owner. I bought it and knew it needed some maintenance. The truck ran good when I bought it drove it around for a few days then I got to work. Did the timing belt, water pump, valve cover gaskets, spark plugs, injectors, starter, alternator, and radiator. Serviced all filters and fluids. Now all work is done and I'm not sure if it's running right. I checked every connector and hose and believe everything is correct. I haven't driven it, only let it come to temp in my shop. Should I drive it? I will attach a few videos so you all can hear. Thank you for your help.

    I'd personally check and make sure those coil packs are seated properly and connected properly as well....I had a similar issue that sounded like that about a week ago after changing spark plugs and one of the coil attachments was loose, it was really running rough...a very easy thing to check as well.

    If you have a scan tool look at the short term fuel trims. Is there a shroud for the radiator fan, if not get one.

    Thank you guys. Still trying to figure out the issue. I don't have a scan tool. About to give up and take it somewhere. I just put a new radiator on it and it seems shorter so my fan shroud doesn't fit. I need to modify it to fit.
