Rough idle

Well heres the problem.

Right after I start the blazer I feel a little bit of a rough idle. If I try to go right after I start it it seems to just bog way down to the point of almost backfiring. If I let it sit for a minute or two though it runs much better.

I am in dire need of a tune up so I am thinking that would be some (most) of the cause, any other thoughts, comments?

I would love to see what your cap and rotar look like.

As soon as I do the tune up I will get pics of the cap and rotor and the plugs so you all can take a look. I am pretty sure thats whats causing my problems. I just wanted some more input from everyone.

I had a similar problem and the check engine light was coming ocasionally. I ended up needing to replace the TPS and air filter.

TPS cost 26$ and the air filter cost 10$

Did it myself took about 30 minutes total.

Good luck!!!
