ok, when im cruising around town and i apply a little throttle the prm's suddenly drop rather than climb....the car will eventually correct the rpm's with enough throttle.....whats going on here?.....no cel either.
no one?.....damn, i though this place was full of t-bird gurus.
well, im kinda steering towars my TC.....but the tranny shifts just fine....i had it flushed a couple months back.....i had a 95 mustang (automatic) a while back, it started doing the same thing, so i had the tranny pan dropped and the filter replaced....no help.....so i doubt its just my tranny filter on the bird (again, i only had it back flushed)....im hoping somone will tell me its just a sensor.
i'd say check your TPS with the engine running. check the voltage with the car idleing and with the middle wire probed (and the negative grounded) and the ohm-meter on the 20V setting check that there is 0.97V @ idle. then as you cycle it upward into higher revs, see if it is a smooth transition to higher voltage readings. it should top out at about 5V @ WOT.
hope this helps.
another question....it has been mentioned that there is a low voltage to the TPS and it can be tested....what supplies/monitors the voltage to the tps?...reason i ask is i replaced my tps and it seemed to only halfway fix the throttle problem (rpm's dropping with throttle application)...so where do i look next.....MAP sensor posibly?....and where is the map sensor on a 97 bird?
edit: ok, so ive been reading that our cars (4.6L) dont have a map sensor??
well after installing the new tps all seemed to be good, but my car idle still drops upon throttle application now and then....someone mentioned somthing about voltage to the tps sensor....and that it may not be getting enough current?
Hey guys. I'm in Ohio, in a county that has e check, emissions checking. Anyway, I took my car for test so I can renew my registration and they told me that the probes they use for the exhaust could not get a reading. So, they would not pass me. Said there is a "sample dilution" and could be...
I don't use the washers much at all, but the other day, I found that the drivers side only came up the window about 1/2 way, with a lot of fluid. I took the cowl panel part way off and ran it and saw there were no leaks in the hoses or fittings. I removed everything and took the nozzle and blew...
OK, first .... I apologize for this moving around. I was thinking "Interior" or "Electronics" ..... then tonight as I was prepping to post regarding my final "fix" .... I noticed the "General Tech" section and upon further review, I think it belongs here so here is where I brought it. :cool:
So I’ve searched the forums, tried solutions to anything remotely close to sounding like my issue, and I’m having no luck.
So we bought our first Thunderbird! Test drove it, loved it, car seemed to be mechanically sound. Well less than an hour into owning it the car decided it doesn’t want to...
When we upgraded our PCV system, we touched upon this subject, and the features/benefits of positive oil control, pressure differentials, inductance, reluctance, Bernoulli, Charles and Boyle, and fluid dynamics/kinetics.
All good stuff, a bit much for my 18YO, but he was into it when he realized...
