2002 GMC Sonoma 82,000 miles 2.2 Engine Distributorless ignition. Developed a clattering in the engine that sounds like it is coming from the valve train area. This has been going on for months and it is getting louder, now there is a vibration accompanying the noise. The engine has excellent oil pressure, runs cool and has new plugs and wires. While at idle the noise is minimal but increases when RPM is at 2000 and above. Has anyone had this similar problem? I have tried using high test gasoline, injector cleaner besides the new plugs and wires. Any advise would be appreciated.

I saw on here a message about an s10 that was sputtering and making noise at idle. I'm having a similar problem and have already put a lot of money in trying to figure it out. Only when at speed and trying to maintain, my engine stutters. A computer check says that #2 and #3 are misfiring. I've recently had a new fuel pump installed, new plugs and wires, a new #2/#3 ignition coil and had the injectors all professionally cleaned (not just fuel additives). My regular mechanic is stumped and I can't afford to give my truck over to a dealership for several days of diagnosing right now. The stuttering does not occur at idle, acceleration or deceleration. It even stutters while on cruise, but not nearly as much. It seems that the instant you release pressure on the gas peddle (while maintaining speed, or during shifting) is when it seems to occur. Any one have some ideas? Thanks

Engine skipping is about the best way for me to describe this problem. It is on my 03 s-10. It only happens when I am at low RPMs and I'm putting my truck in a little bit of a strain. I've replaced the plugs/wires, catalytic converter (took it out), and fuel filter. I have tried these things and nothing has cured it.

I have a '92 S-10 Sonoma with 51,000 original miles. It is a 4.3 V-6, 5 speed standard transmission, extended cab. Has A/C, PB & PS and not miuch else. Every 4-6 month the truck starts running a little rough, even with the A/C off. After about a week or so of this, it won't start, cranks fine but no spark and no TBI fuel being injected. On rare occasions, such as yesterday, I can let the truck sit for a couple of hours, and after moving and fiddlng with the two module connections, the truck will start. It made it home, stalling twice but restarting. Today it won't start for anything no matter what is done to the connectors. Every time this happens, I install a new ignition module and everything is fine for another few months. This is a problem of the last two years or so, before it was perfect. I have replaced 4 modules in the last 18 months. The plugs are relatively new, the wires the same. Have run the truck at night with the hood up, don't see any sparks or lights. The ignition module connectors have been cleaned and lubricated, they are tight when installed. The proper grease is used under the module, it is tightened evenly and snugly, but not overtightened. Does anyone have a similar experience or see something I am missing? Thanks.
