i searched last night for some info, found similar topics, but alot of them didnt have the solution once it was fixed..
at 1/2 or 3/4 throttle, the motor is fine. drives fine, hits vtec, no problems

motor is a 95 gsr-completely stock

once its at WOT, no matter what RPM it shuts down- doesnt shut off, doesnt gain/lose power, totally shuts down and does nothing..

i changed my head gasket and put a new throttle body on, and since then its been doing this..

***********IM NOT THROWING ANY CEL'S**********

this is what ive done so far to try and correct it:
changed spark plugs
changed spark plug wires
changed dizzy rotor
checked timing 4 different times
ive checked my vacuum lines, dont see anything wrong or not hooked up

please help.. anything you can think of

 

tps?

 

wouldnt that make it run like crap all the time? or at least throw a code?

 

fuel pump is going out

That would be my guess

 

fuel pump has been replaced when i bought the car like 7 months ago..

 

My first pick would be TPS given the circumstances tha tyou are describing.

Do you have access to a volt meter so that you can check/adjust the TPS. At least that way you can rule out the tps at no cost.

With the ignition on car not running the closed throttle voltage should be approx 0.5v and the voltage should move up gradually to WOT @ approx 4.5v. Get yourself a haynes manual if you don't already have one. This proceedure is in the book. I don't have the time right now to write up what wires to check or the exact proceedure.

Get the TPS out of the way and then go from there.

 

first try swapping your tps and map sensor plugs. It won't throw a code if they are mixed. then check tps with volt meter then swap you fpr if the first thing doesn't work.

 

get that tps done yet?

 

it was the TPS sensor.. i just never figured it could be since it didnt throw a code.. the green and yellow wires were switched around-switched them back and now everything is fine.. thanks for all the help guys!!

 

good to hear
