Yesterday, driving and my car bogs down violently. (in a neighborhood) I look at my tach and I see my idle is down to 0, then the car's CEL pops up. Won't restart for a while, then I manage to start the engine. I drive around the neighborhood and I have the "limp-mode" 3k rev limiter, and I basically have no idle. I have to ghetto-style drive the car, using the e-brake a bit, and lightly gassing, idle-ing the car myself 'til I get home.

Today, have to drive the car to school, same problems. But later in the day, the CEL goes off and the car seems to run fine! I went to the nearest autozone anyways to get them to pull the code and what I get is a P1128 "Fuel Air Metering". I did a search on this, and only found one other person with the same problem as me, but his problems got better temporarily, then his car wouldn't even start anymore. (hopefully not the case for me). Can anyone tell me what possibly needs to be done? Sorry for the long post!

Thanks!

i read P1128 MAP lower then expected. Have you tried the "map whack" and reseting the ecu yet?

WeezyBaby

I did map whack a couple times actually since then. Haven't reset the ECU though. Does resetting the ECU do anything worthwhile? (resetting ECU is the 30-second fuse pullout thing right?)

silencertk

it resets the ecu lol. yeah pull the fuse for about 15 sec and i'd disconnect the map clean it off, clean the "hole" off and then replace it. From what i recall though you could just be needing a new map. but i'm no expert.
clean the map-->reset ecu-->close eyes--->start it up and hope
good luck

Thanks alot bud I was reading about idle air control valves and what not, I hope it is, just a bad map sensor. I also have been having kangaroo-ing movements while trying to accelerate, i'm always finding myself map-whacking every few days.

silencertk

could be that you map whacked it dead lol. Like i said, i'd order a new one, clean the old one (may not do you any good but oh well) reset the ecu and hope for the best. keep us updated
