If I was you I would do the proper maintenance like cleaning your throttle body a tune up do the spark plugs all The Usual Suspects as far as a complete tune-up goes, cleaning out the throttle body putting seafoam in your gas tank seafoam through the throttle body stuff like that to try to clean everything up and chiefly your spark plugs need to be in good shape try those things first and then get back to us

I did the spark plugs and cleaned the throttle body also put fresh fuel in. Looking at the throttle plate , it is as soon as it starts to open and gets a bit of air that it bogs out ... thinking it may be a fuel issue?
Yeah I think there's an additional thing that you have to do the throttle position sensor or the equivalency of that year model has some other name to it but that also has to be cleaned you want to make sure that you're getting fuel pressure to your fuel injection and I think it's a TPS "TPI" sensor throttle position sensor or it's under another name for that older vehicle but you want to make sure that's in good shape too good luck
