I have been pondering for days on what my problem could be with my car. I have replaced/done alot of things and the problem is still there. First let me explain what my problem is.
When i press the gas pedal the car gurgles.. example:
ya press it, it sounds like it will stall, until ya goose it, then it goes.. this happens everytime i stop and go. and even in reverse it happens.
I unhooked the map sensor and it run somewhat fine.. from what a setted value in the ecu is setted to.. but it doesn't run totally fine. I replaced the map sensor.. now when hook that back up when the engine is running it turns right off.. i guess meaning the map sensor works and something is faulty somewhere else..
These are the things i have done to the car so far..
Replaced all spark plugs, did a volt test on those.. 100% ok there.
Replaced the map sensor.. i guess it is good. don't really know how to test it..
Replaced air filter..
Cleaned throttle sensor so it moves freely. since it was covered with carbon.
Put 3 bottles of fuel injection/intake valve cleaner (valvoline) in my gas tank and ran that for a week.
When the map sensor plug is off.. there is very little stalling when pushing the gas pedal..however when driving it sounds like it is downshifting/something pulling.. which i am assuming it would be not the correct air/fuel ratio. just the set value..
If you need to know more i can tell ya.. i am not good at explaining this problem, as i am no mechanic.. but if you could give me some hints or tell me what the problem is, i would very much appreciate it.
Oh another thing, when starting the car, it won't start up.. it turns over but no start. it'll start after spraying starting fluid in the air filter intake.
Weird car, weird person.. things like this always happens to me. ;|
Thanks,
Mike

What happens when you put the old sensor back in? Are you sure that
the new part is the right one?

Too much. More won't make it clean better, but it can damage your
engine/fuel parts.

Did you put a new fuel filter on? Is the fuel pump working? How about
the PCV valve? O2 sensor? Check for exhaust blockage? Did it ever
overheat? Any computer codes? What year is your car? Engine size?
Accessories?

Sounds like it would be worthwhile to have a mechanic inspect it.
OK you dinked with the MAP sensor but how about the MAF sensor?
Kinda sounds like that to me especially since its hard to start. With the
motor running you can tap on the MAF a bit with the handle of a screwdriver
or something and listen to see if it gets a bit better then rough again.
