i have a 1991 accord ex that i bought and i need help. i have done alot of work to it by reading post and stuff...this is what i have done.

new fuel pump
reman distributor x2
new rotor and cap
new wires and plugs
head job
new main fuel relay
new pvc
cleaned out the idle contol valve
new timing belt
new water pump
new o2 sensor
new fuel filter...new thermstat
think that is it...lol

something to note..got car this way before i got work done....when i plug in the sensor for the temp guage it goes straight to hot...so i have it not connected. they put a aftermarket temp guage on becuase of this and it is put where the a sensor goes on the water outlet housing in front of engine(top radiator hose).

this is what my car does....starts right up and drives perfect plenty of power..i mean no issues..after it warms up my tach will bounce around..sometimes to 0 which then i lose power but car is still on. sometimes it will kick back to normal or somtimes it will die....when it dies it will start right back up with it dying right away..but aster i couple of tries it will stay running..but still acts up immediatlly. NO CEL


any help would be appreciated? i am lost lol

 

check the voltage from your throttle position sensor. should be .50 volts closed throttle and 5.00 volts with the throttle wide open. do this test with the key in the run position withe engine off. jumping the blue 2 pin connector under the glovebox or passenger kick panel should give you a code 7 for low or high voltage from the TPS. hope this helps

 

k i did that and came up with 41 ...o2 sensor changed it and now the CEL is off.
i will check the tps voltage tommorow...thanks.

 

AFTER SOME MORE RESEARCH...I CHECKED MY ECU GROUND AT THE THERMSTAT HOUSING. IT WAS REALLY LOOSE(LOL HAD THE COOLING SYSTEM DONE BY A MECHANIC WHO CHANGED THE THERMASTAT AND HE DIDNT TIGHTEN DOWN BOLT). I TIGHTENED THE BOLT DOWN AND PRESTO MY HONDA WORKS PERFECT.

SO DONT FORGET TO CHECK THE ECU GROUND AT THERMSTAT.
