I hear a loud vibrating noise from tranny tunnel, mainly when RPM's are a little high and I let off gas pedal. If I engage clutch or step on gas pedal it goes away. have new muffler and pipes. heard it could be cat. converter has gone to pieces. 2. noise is a tapping or ticking noise constant from engine. I assume a flat spot on lifter or valves need to be adjusted.

water leak at the rear of the engine!

what could b another problem why the truck is getting no voltage and draining when i have a new battery and alternater

fan fell off and I am trying to put it back

Got a used 96 Trooper 2 months ago. Running pretty good then one day couldn't start the engine. First I changed the battery. Seemed like that was the problem, then after a week, same problem. I turn the key, it started to crank, then it died.The dashboard went dim, then no power. Waited 20 minutes, crank the key,power came back but it won't rev the engine. Can hear fuel pump working. Might be alternator or starter. Has anyone gone through this?

Truck all of a sudden turned off and is hard to start. Once it starts idle is rough and does not have enough power to move. Replaced fuel filter but did not help. It has alot of white smoke coming out of tail pipe. No check engine light on. Just started this today. Please help!

was working saturday sunday am was going to store turn off had to put gas all the way down be for no need to low r.p.m will not move new fuel filter

change maf,plug to it checked volts,dont know


I can push into a heated garage and after 2 hours it will start within 3 seconds. this is the 4th time/event. Battery/ starter/fuel pump/compression/plugs all ok. I have added "heet" to gas. NO check engine light goes on so I have not plugged it in for codes. Which sensor do i start with? Mass Air flow- MAF, EGR Valve/Sensor, camshaft position sensor CMP, __A. is there a Coolant Temperature Sensor (CTS) that tells the PCM what the engine temperature is. If it is reading hotter than the actual temperature, the PCM will provide the wrong air/fuel mixture for a cold start?
Runs great once it is started, it will restart if it has been outside less than 5-6 hours it depends on the outside temperature.

Had the check engine light reprogramed

this has happened 3 times on hills one machnice said it was fule enjecktion another said its a part that cost $800. what do i do?

Turning the key on and off several times seems to help.

car idles fast and have tried everything ,was showing codes of P0300,P0174

Just put on new MAF sensor and now this code is showing. Whats up

my trooper would not pass a emisions test after replaced the ekg valve the check engine light went off but the dmv said it needed a drive cycle. how can i check this is complete before i take it back to the dmv for retest.

Can both these codes be caused by the mass air flow sensor

Would you know where one is? One where I won't get ripped off cuz I'm a girl!!

It is continually flashing off and on CHECK

vehicle will not fire or start. Where is he fusable link located on it?

I was told that I have to replace the intake manifest casket. Can this be the reason why the check engine light is on and why my car is shaking?

The reverse lights are intragrated in the neutral saftey and I don't want to loose them.

or is it something else

serious grinding noise when moving slowly

starter good. ign switch good. will not crank. Relay does click when turn key to start. no power to starter solenoid.

I bought this car not running and was told the computer is bad. I want to be sure that is not a bad ground or fuel pump. I checked the fuses, the fuel pump does not come on with the key. I also tried some starting fluid and it made no difference.
