rough idle
i put in a new cap, rotor, and wires
but my engine has a good idle but is really rough it shakes the whole truck and uses alot of gas i get around 5 mpg and i can smell gas through my firewall when i am driving, and at a high rpm it sounds like there is a rattling in the bottom of my engine. what do i need to do to fix it? its a 1989 s-10 blazer 4*4
*combining consecutive posts*
also while i am driving it act like it has no power(pick up) and i am not hauling nothing. i step on the gas and it goes nowhere, it almost acts like it wants to cut off then when i get to my house from work a 15 min drive a soon as i come to a stop it cuts off by itself. what do i need to do it fix it cause i cannot afford gas at 5mpg.

RE: rough idle
I had a similar problem. My truck was blowing gas through the exhaust and running really bad. It turned out to be a bad CPI unit. I had to take off the intake manafold and change out the whole unit. I replaced the EGR valve while I was at it as my truck was throwing a code indicating that it was bad as well. It cost about $380 for all the parts. The CPI unit is a common problem. Lindertech.com was a good write up about it. Check it out and see if it sounds like your problem. That's where I bought mine. You can also get it at any auto parts store. Check your tail pipe. If it's wet with raw gas, you may have the same problem.

RE: rough idle
i changed the cap and rotor at my friends house and drove it home and it was fine when i got to my house i changed the plugs and i think i put the wrong plugs(it started right away ideling rough) so i put the old ones back in and it didnt help anything.so it started doing that right away after changing the plugs.well the next day my father-in-law had the day off so he put the right plugs in and bought new wires and a couple of boxes of vacuum hoses(havnt used them yet) but after he worked on it it still having the problem
