i have a 88 crx dx with a d16y5 single vtec it runs fine untill the throttle is wide open then it bogs out like the motor shuts off or something then when i let up a little then it goes again anyone know why this could happen??????????

 

when was the last time the plugs and plug wires were changed?

 

about 4 months ago i had them in my other engine when i blew it same with the wires, ill try to change those right now then see any other suggestions???

 

It sounds like you aren't burning all your fuel which is causing it to bog at wot. Make sure the plugs are gapped correctly as well. What condition are the plugs in? My B16 did this and all it was was the plug wires.

 

ok well i just put in new plugs and it still does it, it has to be a switch inside the car on the pedel or something because i even loosened the throttle cable to where the pedel dosent even open it all the way and it still bogs but as soon as i lift the pedel up about an inch then it revs fast so i donno..

 

Check the map sensor and the IACV. There isn't any switches by the gas pedal. Are all the vacume lines done correctly?

 

go through all your ignition stuff and clean clean clean,

cap,rotor,etc......change the wires with a buddy just to see..etc but sounds lide an ignition issue

 

How about the TPS. Sounds like a textbook TPS problem to me.

Check it with a voltmeter. the middle wire is the signal wire.

Turn the key to the on position and connect DVOM and move the throttle very slowly and watch the voltage it should rise slowly. What you want to look for is a position where there is a drop in voltage..

Good luck

 

yeah lines are correct but also i dont have a charcol canester and i just left all those lines hanging could that be the reason? or could the canester be the reason why it smokes?
and by the way its dpfi.. thanks

 

oh and it throws code 14 which is iacv i think and i put a diff one on but still throws code so i donno..
