I'm Awesome
This topic is all too often heard but I can't find out the problem with my truck and I dont want to go about spending money that I didnt need to.
Now the problem:
About 4 months ago when I started the truck cold, it would idle around 1500-1600 rpms. And from that time to now it went down to 1000-1100 rpms cold.
When idling the engine would almost miss and the rpms would drop to 450-500 rpms then raise to 800 rpms and then back down to about 650. This would happen about 6 to 8 times a minute.
During acceleration: if it is a VERY slow acceleration, nothing happens and it runs fine. But if I drive it like I normally do it will shudder for a split second (Shaking the engine and the truck) and then run fine. after about 800rpms.
this ONLY happens when the truck is warm. When it is cold, it runs like a champ.
and my mileage took a HUGE dip when I changed the plugs. I went from (the day I bought it) about 14 city. to about (4 to 6 months ago) 10mpg. and that of today where it is stupid. I can get about MAYBE 100 miles to half a tank.
Now here is the funky part; If I drive it nicely that crap happens. But If I drive it like its stolen it runs just about perfect at idle and acceleration.
What the heck could this be? I'll see if I can post a video or something cause this is annoying and I want to start driving my baby again. I hate my malibu.
