408h22a1

ok i bought a h22a1 prelude a week ago its been running like a champ until today it started to bogg on me the harder i hit the gas then once its past 3500rpms it seems to start pulling again i dont know what the problem is i check all the plugs and there getting spark when i first start the car in the morning it runs perfect for about 10-15 min then it warms up and its back to bogging dosent die on me it idles at 1k perfectly without studdering or jumping but once i start to gas it about 35% you relly feel it bogg ive ran it down to empty a few times thought maybe i clogged the lines but if i did wouldnt it be the same when its cold? if someone can help me id greatly like it thank you

Exactly what kind of car do you have ?

408h22a1

1993 prelude vtec model

prelude447

maybe start off easy and just change the fuel filter there easy to change and cheap

408h22a1

if it was the fuel pump or filter wouldnt it run messed up when its cold too?

prelude447

not sure the engine could be loading up to sence it doesnt clear out till about 3500 do you have a bad valve cover gasket?

408h22a1

in a way yes but no i bought the car and its missing the front left bolt they rigged it to not leak with some type of gasket sealer but its not leaking any oil from the gasket if thats what you mean i was thinking mybe the throttle sensor?

408h22a1

think i fugred it out im pretty sure its the throttle position sensor when its pluged in it can rev from 3500-7000 rpms perfectly when its un pluged it boggs the whole way up not just at 2-3k

prelude447

ya i was saying maybe ur burning oil cause it could be leaking onto your heads but i you igured it out than thats great

I would replace the oxygen sensor with Denso OEM from rockauto. If it still does it, then clean out the egr ports and egr valve.
