1994 Chevy Blazer K
 

I have two chronic problems with my Blazer.

1. When I press on the accelerator, i get an initial jump, but the engined then boggs for a second before resumingnormalacceleration.

2. I have plugs that fowl about every 6 months.

I would love your input as I am no mechanic. Thanks.

Sounds like its running rich. You could possibly have a clogged cat converter.

How do I fix it?

RE: 1994 Chevy Blazer K
 

We are talking K5 blazer arent we?

You can replace the catalytic converter to fix a problem with that.

Flooding problems will correct themselves most of the time, but if it doesn't you can adjust the choke.

RE: 1994 Chevy Blazer K
 

Indeed it is a K5. Is there any way to clean out the existing one? I don't have much money to play with.

RE: 1994 Chevy Blazer K
 

Never had to do it man. It may not be the cat at all. It may be something as simple astiming. Its hard to tele-diagnose that problem.
Next time you take a fouled plug out, take a close-up picture of the end of it before you clean it. It can be really helpful in finding out what the problem is.

I would love to hear some other opinions. Thanks.

doesnt sound like the cat but if u do have problems with it take it off and punch a hole through it from one end to the other. it sounds like a fuel problem to me but that shouldn't foul the plugs try using a hotter plug and see what it dose

RE: 1994 Chevy Blazer K
 

what plugs do you use? If they are Champion or NGKplugs, throw them in the garbage and get some ACDelco or Bosch plugs

RE: 1994 Chevy Blazer K
 

I assume it has TBI
Sounds to me like you should check the timing, may be retarded slightly and also if you know someone with a scanner see if the tps is working ok

RE: 1994 Chevy Blazer K
 

Good point.

RE: 1994 Chevy Blazer K
 

in your opinion, where is the best place to buy plugs? The best deal I mean. Also, as I said, I'm no mechanic, so what does TBI and TPS mean? I know that's a stupid question for you guys to have to answer, but I'd rather ask it on a computer rather than face to face. Save a little embarrasment. Thanks.

RE: 1994 Chevy Blazer K
 

I usually buy my plugs from Autozone or Napa. Most auto parts places will have about the same price.

I made a list of acronyms and abbreviations in the general tech section... https://chevroletforum.com/m_48092/tm.htm

TBI/CFI--- Throttle body injection & central fuel injection (same thing)
TPS-- Throttle position sensor

How do you adjust the choke?

RE: 1994 Chevy Blazer K
 

I would say the one plug is fouling out because of a bad valve guide and the throtlle response is timming or stopped up filter

you dont.
