Loud Tick, Bad Idle, and Trouble Starting
So my DSM has just gotten to the point of me not caring about tuning anymore and just caring about keeping it running until I can afford a new car.
It's got 175,000 miles on it, paint is chipping off, rust is appearing, and everything just seems to be breaking. I haven't messed with any engine internals - all of my mods are just bolt on. So here we go....
Problem 1: Loud Tick at idle (lifters)
Suddenly I started getting some really loud ticking noise that sounds exactly like lifter tick, but is now much louder than before. It only happens at low idle (around 1,000ish) and goes away once I get the RPMs up to about 1,500. What could this be? Is it just lifter tick? Should I be concerned? It doesn't bother me too much, it's just a bit annoying and embarrassing... like the rest of my car.
Problem 2: Rough Idle
I know, this gets asked a million times on this forum...
It could be a boost leak, but I doubt it. I just fixed a bunch of leaks recently. I'll test for it regardless...
It almost seems like it's missing fires on the spark plugs or something... When I'm not applying gas it just seems like it coughs. Whether I'm sitting at idle or if I take my foot off the gas to slow down. My spark plugs are only about 8,000 miles old, and my plug wires are 23,000 miles old so I doubt it's misfiring due to those...
I also replaced the Idle Air Control Valve 10,000 miles ago.
Problem 3: Trouble starting at times
A few times in the past month or 2 it's really turned over a lot before starting. It's only happened a handful of times so I'm not too concerned yet... but those times it seemed to start right up when I pressed the accelerator. Could this be a starter? Fuel Injectors?
Anyway, thanks for your help. I appreciate it.
