Car bogs down or chokes!

[Firebirdbabe420]

Alright... my car started "hopping" on me or boggin down. we replaced the fuel filter which only lessened the problem. it still hops at normal driving, but repeatedly hops and chokes when im under load, i.e. in fifth gear going up a hill pushin down on the gas. just seems 100 times worse that way. What could be the problem? fuel injectors or some god knows what sensor? please help! [img]graemlins/fluffy.gif[/img]

mine just started too (70k miles).

change your spark plugs and wires. seems to be a common problem when one of them goes bad.

spark plug wires, happened to me around 50K miles not a biggy but it sounds like your engine is going to die on you all the time :D

Same thing here. Replace the wires and plugs while you are down their. Some of the plugs will have damage from the faulty wires. Mine did at 50K. You can get a custom set of wires for around $40

Same thing happend to my 98 at about 55K. I ended up having the plugs, wires, and ignition coil replaced. On the diagnostic it was reading as a "Random Misfire". Luckily they covered it all under the extended warranty.

There was also a recall on the plug wires for I think it was 96 to 99 v6 fbodies.

My engine isnt dying on me yet, it just bogs down and hops. ill try the spark plugs and wires. any tips for easily accessing the damned things? am i going to have to jack up the motor or what? i cant reach em from the top or bottom. [img]graemlins/fluffy.gif[/img]
ps... i also have 110,000K on my car, could there be something worse?

Mine did the same thing around 50k, bad plug wire, but it did throw a code, are you getting a ses light?

[Firebirdbabe420]

I did have a ses light come on but that was for my bad cat. replaced that and the light went off. thats why im wondering if its something that doeesnt show up on code readers. its such a crazy feeling... i unno. but what i dont get is why this has happened to all you guys at 50K... mines Just now happening at 110k????

Definitely spark plugs/spark plug wires. Had the same problem when my car hit 60,000 or so. Felt like it was choking...Going slow was fine, but when I got on it, there was popping from the exhaust and really, really slow acceleration, and plenty of hopping, like something was holding it back. Replaced plugs and wires, and ran stronger than ever.

If not your wires and plugs change the coils I bought 3 coil packs from summit (MSD coil packs) for about $38 each I would change those anyway *shrug* Yes you'll have to jack up your car to reach all the plugs unless you have super flexible arms you'll never reach the passenger back plug I got all but that one, from the top of the engine

Thank you a lot guys. After about three hours, spark plugs and wires were officially changed. now my car runs perfect! [img]graemlins/fluffy.gif[/img]
