Having problems with your 1997 Lincoln Town Car ?

I have a 1997 towncar I had a plugged convertor, the second one i cut a patch out and cleaned it out, welded it back up, now i have a check engine light on. The oxygen sensors are in front of the converter. My question is this going to mess with the air fuel mixture? And if it will how can i bypass the second sensor or trick it into what it is supposed to read? Thanks, Mike

Answers :

It won't mess up the a/f ratio. The Check engine light will be on because of the rear O2 sensors. To keep the light off you will need to install O2 sensor simulators.

Definetly, you have to check injectors electrically as well as physical condition, also the harness for injectors is a common cause check for a break in the wires take your time go through harness little a time checking for cracked wires. ... 1997 Oldsmobile Achieva

Just replaced my dirty fuel filter last week, after replacement its noticed in hard restarting for almost 1 day used. For the second day in the morning I started my Starex CRDI 2005 model and won't start until now. What are the posssible defects since the fuel filter had been replaced with new one? I pump the fuel filter pump just to removed the air bubbles, It has been successful, there's a fuel going to fuel pump.Please help of what are the specific defects with my crdi engine.

Well if the fuel filter was plugged it has already caused damage to the fuel pump, first thing you need to do is check to see how much pressure is getting to the fuel rail, then check the volume, if this is all ok then you may have a dirty injector.. ... Hyundai Tucson

I own a 03 jeep wrangler TJ 4.0. At high rpms or under load (going up hills it looses power) if driving in 5th gear at 60 mph and is down shifted to 3rd gear it slows down extreamly, the engine will not go past 3200 rpms. Not moving if rpms can only go to 4200, past that it boggs down, as if it were getting starved from fuel or air. I have recently installed a high flow exhaust system that removed the two catalytic converters that were just past the headers, and i have been told it could possibl

I have a 97 blazer with 186000 4.3,it stalls when it gets warmed up.I have replaced 2 O2 sen.,EGR,mass air sen., and wires,rotor and cap. I have checked fuel filter(clear) Cat. converter,and fuel pressure engine off is 60lbs engine at idle 45 lbs this is a CSEFI system.Is my pump bad? Or is there another thing going on


Hi,\015\012It was something that takes a lot of time and money to diagnose.Emissions requires the truck to have an EGR valve (exhaust gas recycle) and this deposits gunk (carbon residue) on your MAF (mass air flow sensor) If you catch it in tim ... Chevrolet Blazer

My 94 full size blazer starts and idles fine in park and in neutral. When I put the truck in gear and hit the gas, it'll start, then act like it wants to die. The Catalytic converter is off, I'm going to get that replaced. I've done the basic spark plug/wire/distributor cap replacement. Last year I changed the EGR valve. I changed the ignition coil today. Put on a new o2 filter. New fuel Filter. New k&n air filter. Could it be a bad fuel pump?

I am having fuel probems with my 2002 Dodge Caravan, 220,000 Km. I had a bunch of work done on it, spark plugs, spark plug wires, distributor, catylit converter, fuel injectors, air filter, and it is still running rough, smells like gas inside the van, and is wasting around $ 80.00 for 120 km, used to go 700 km for that amount of money, any advise


If you smell gas inside of the caravan, then something is wrong other than a tune up. You need to have the gas tank, gas vapor recirculation, gas lines, in-line filter, and gas filler tube examined. It could be linking in any one of these places. ... 2002 Dodge Caravan

I have a 97 ford explorer 5.0, I replaced the camshaft synchronizer on it. The guy that was assisting me pulled the old one out while I was looking for a paint marker to mark, therefore it was pulled incorrectly. I tried finding TDC and drop it in and it still won't crank. Also, we sprayed fuel in the throttle body and then it would crank and run very rough for a few seconds before going down. My question is is it out of time, and if so how can I fix it? Also, it seems as I the fuel pump has w

Runs ok except at 4000 rpm or above..... it throttles down and right back up to 4000 rpm..... it does this every two seconds and as long as I hold the throttle open to 4000 rpm on the tack,it will only stop doing this when I go to 3900 rpm........ it runs as smooth as silk.......... feels like the fuel is disrupted at 4000 rpm........ just bought the car, so I don't know when the fuel filter was changed...... we changed the air cleaner..... it was so dirty, the car ran noticeably better after th

O.K. here it goes. I have had struts replaced, new Harmony Michelen Tires, spark plugs and wires changed, fuel filter and air filter replaced. Even changed the tranny with a spare I had left over from a wrecked Le Sabre. Here are the symptons. Even at idle sitting at a stop light it will flucuate between 750 and 1000 r.p.m.s Kind of jerking back and forth every 10 seconds or so. Then when you try to take off at a nice smooth acceleration it wants to hesitate and just not go like normal.


Hi! I believe that the fuel injectors got nothing to do with it. I suspect that you have a faulty MAF (mass air flow) sensor. This has big contribution on engine performance specially the idling. Please check the ECM and PCM too, for these are the br ... Buick Park Avenue

Thank you for the input as far as your beliefs about it not being the torque converter as I was about to purchase one and have it installed. My question is what could cause this to be happening then? before I turn this engine over again and cause more damage that might have already occured in the fifty miles this second time around, I need to know what could possibly be causing the first crank and Main bearings to go as for sure now we know it wasn't a factory defective crank if the noise is sta

I have 97 Acura RL 3.5/V6, got 'Check Engine Light' on (OBD Code P0740) about a year, my car is running OK, except slightly low fuel economy (19 Miles/Gallon). My questions are: 1)Could it be just Solenoid problem or bad Torque Converter (need to rebuild Transmission)? 2)if it's Solenoid problem and I keep driving without doing anything, will Transmission go bad eventually? 3)To rebuild Transmission will include Solenoid replacement? Any suggestion would be much appreciated!
