Hello
The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

SOURCE: 76 volvo 240 car idles and low speed is rough,

It could be the filter. Has the fuel been changed after storage? I would also thing the Carburetor or the fuel injectors might need to be cleaned.

SOURCE: My 94 z28 camaro chuggs when i punch it

sounds like a fuel pump struggling to pass its contents. try running a treatment solution in your tank. if this fails to work, you will need a new fuel pump to correct this problem. sometimes, trash will build up in your tank and it will cause build up in the jets. you should check vacuum as well if needed.

SOURCE: 1999 SL1 running rough

Had a similar problem; started fine but lost power under acceleration and would stall. I changed the fuel sensor relay in the fuse box located on passenger side of interior fuse box. Ran fine after that.

sounds like the iac might be giving problems, check ur idle air control valve on the side of you throttle body if its working right, replace if not.

Try changing out your distributer cap and rotor button. Let me know if that solves your problem.


Thx

The truck will run great as long as i am on the gas and going as soon as i slow down to come to a stop it will want to choke out it would seem like. it stalls out unless i put it in neutral, why?

had this exact thing occur in my car a couple of days ago. I lifted the bonnet and the air filter pipe was blown off from the filter box and a hole was in the box the air filter sits in. This was caused by a back fire problem my car has . I put the air filter pipe back on the box and have a piece of timber and gaffa tape covering the huge hole and my car runs ok until I can yet it serviced and fixed .

My 95 dodge ram 1500 with 5.2 starts and idles fine but when im driving it around 25 to 55 it wants to start chugging like when your in a stick shift car and your in to high of a gear for your rpm and it...

Me thinks it needs a tune-up. You can do it yourself. This guy is old enough. But hubby is the expert. Will sent your problem to him. A tune-up equals shake out the air-filter - knock it against the curb. Then check the plugs, and their gaps. If it has those. Back in the day, we used to be able to work on our own cars. Driving a 95 Odyssey with a Real Carb, and real tranny. Ergo, this might help. - JW

Idle surging chugging weird problem READ!!

hey common problem w/the 2000 galant. you may need a mirror to see this, look and or feel where your throttle body mates up to your intake manifold. it has a problem of cracking, when you have an air leak there it will run like **** and usually shut off depending on the severity. this will cause you to get the throttle position malfunction code. if that is the case instead of buying a new or used intake manifold. take the old one off, and you can actually cut it flush and weld about a 2 inch in length tube to repair the crack. well let me know how it goes.

Pontiac lockup converter

A GM dealer should be able to reflash the PCM to help alleviate the chugging.To a certain extent,it is normal,and you might want to consider tuneup things like plugs and wires,air and fuel filter,and also have all the engine and transmssion mounts checked for weakness,as weak mounts will magnify these types of problems.
