seth3030 Posted August 11, 2009 Share Posted August 11, 2009 i have changed the fuel pump and filter, and the o2 sensor to see if it would help my problem, going up hills and pushing down the gas to keep it at freeway speeds or sometimes slower, seems to happen more often with more weight in the car, it sputters really bad and rumbles sometimes i can keep pushing the gas and it takes a few seconds and goes away but sometimes the car fully dies, give it five min or so starts back up and the rumbling is gone. so confused!!!!

89Ru Posted August 11, 2009 Share Posted August 11, 2009 rumbling...maybe you are losing one (or more) cylinders? does it sputter constantly or just once in a while? any ecu codes? Quote Link to comment Share on other sites More sharing options...
Rooster2 Posted August 11, 2009 Share Posted August 11, 2009 Have you changed spark plugs and plug wires? Also, add a good can of injector cleaner like TL-3 or Chevron Techron. Cost is about $6/can. Don't bother using the cheap injector cleaners costing $3 or $4/can. They don't work very well. Quote Link to comment Share on other sites More sharing options...
seth3030 Posted August 11, 2009 Author Share Posted August 11, 2009 it does not sputter very often only every once in a while going up hill usually, no check engine light, it came on once and hooked up the black wires under the dash and it gave me a 32 which said it could be the 02 sensor, losing cylinders? that doesn't sound good :/ Quote Link to comment Share on other sites More sharing options...
seth3030 Posted August 11, 2009 Author Share Posted August 11, 2009 it has been about a year or maybe two since spark plugs and wires have been changed Quote Link to comment Share on other sites More sharing options...

That has happened to me in the past, and finally I figured out the gas that I bought had some water mixed in with the gas. Suggest adding a can of "dry gas." If you don't know, that is a generic name of a product that is designed to help rid your gas tank of water or moisture. Any retail car parts store will carry the product. It is inexpensive, and worth a try to see if this will help solve your problem. Quote Link to comment Share on other sites More sharing options...
seth3030 Posted August 11, 2009 Author Share Posted August 11, 2009 ok thanks i will try it and let you know what happens Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted August 11, 2009 Share Posted August 11, 2009 Change your plugs and wires. Your are probably seeing it mostly on hills and "loaded" because that's when the engine try's to richen the mixture for power and your are not getting proper ignition. These engines seem to like annual plug changes - the wires are cheap so I generally do both. GD Quote Link to comment Share on other sites More sharing options...
seth3030 Posted August 12, 2009 Author Share Posted August 12, 2009 changed plugs and wires, went right out to a hill tried to make it up without the stumbling didn't happen, going up the hill it started losing power and right after the hill it started to stumble so i let it idle for a while while my car was rocking around then maybe a min later the rocking stopped and it was fine! this is getting annoying hahaha Quote Link to comment Share on other sites More sharing options...
Olnick Posted August 12, 2009 Share Posted August 12, 2009 this is getting annoying Amen to that! A longshot: Engine Coolant Temp Sensor need replacing? Question: Did you use NGK plugs & OEM wires? Quote Link to comment Share on other sites More sharing options...

Mugs Posted August 13, 2009 Share Posted August 13, 2009 Try the HEET treatment (the water remover in the tank) also maybe a seafoam treatment. One in the tank, half a can in the crank case, and another fulll can through the intake. I made my own "delivery machine" with a 20 oz soda bottle some vinal tubing and an in line peck cock valve. Can take a pic and show you if you would like. Quote Link to comment Share on other sites More sharing options...
Mugs Posted August 13, 2009 Share Posted August 13, 2009 Hey this is just an after thought. But your cat may be starting go out/getting clogged. Thus it is loading up under hard accell and then "cooking" back off and clearing out after the "load" has gone away. Just a thought. Quote Link to comment Share on other sites More sharing options...
seth3030 Posted August 13, 2009 Author Share Posted August 13, 2009 just put the water remover in the tank so we will see, you thinking it my be the catalytic converter? Quote Link to comment Share on other sites More sharing options...

seth3030 Posted August 13, 2009 Author Share Posted August 13, 2009 A longshot: Engine Coolant Temp Sensor need replacing? could this cause it to do that? yeah i was thinking the coil too but i am not sure, and they are about a hundred bucks Quote Link to comment Share on other sites More sharing options...
Cougar Posted August 13, 2009 Share Posted August 13, 2009 (edited) The throttle position sensor and MAF sensor are other suspects that should be looked at. A partially plugged CAT is possible also and may explain the rumble noise you hear at times. Edited August 13, 2009 by Cougar Quote Link to comment Share on other sites More sharing options...
seth3030 Posted August 13, 2009 Author Share Posted August 13, 2009 there hasnt been any noise it just starts rocking the car when stopped or idling after going up hills, how would i test to see if its a maf or tps? Quote Link to comment Share on other sites More sharing options...
bheinen74 Posted August 13, 2009 Share Posted August 13, 2009 i've got spare coils think they are all good, they usually run about 15 or 20 at a junkyard. Quote Link to comment Share on other sites More sharing options...
Olnick Posted August 13, 2009 Share Posted August 13, 2009 A longshot: Engine Coolant Temp Sensor need replacing?could this cause it to do that? No guarantees but it's a possibility. When the ECU gets poor/no temp information it will default to open loop (I think) and cause the engine to go all wonky. It's about $30 IIRC. Or at least it was a few years ago! Replaced mine when having some rough running and stalling problems and that pretty little EJ22 ran like new. And here is a two-for-one trick: Take your IACV for a thorough cleaning, while it's out you have a clear shot at replacing the Temp Sensor! Good luck.

Fairtax4me Posted August 14, 2009 Share Posted August 14, 2009 there hasnt been any noise it just starts rocking the car when stopped or idling after going up hills, how would i test to see if its a maf or tps? This "rocking" sounds like it might be a misfire. My Lincoln does exactly what you're describing when there is a coil going bad. But it usually sets a code for a misfire after a few times. Have you replaced the fuel filter recently? Quote Link to comment Share on other sites More sharing options...
seth3030 Posted August 14, 2009 Author Share Posted August 14, 2009 yeah fuel filter changed about two weeks ago Quote Link to comment Share on other sites More sharing options...
