HELP! CEL-- car is puttering
Hello,
A couple days ago my CEL came on, and I noticed that my car now idles rough. It also vibrates under acceleration, especially under 2.5 rpm. Once I reach 2.5 rpm the vibration is hardly noticable. Has anyone run into this problem before, or know how to fix it? Thank you in advance for your help |
You should post the CEL code along with the problem. I think there are shops that will do it for free, for me, it was easier to buy a diag reader from Auto Parts Warehouse.

I got the code, it's P0302: cylinder 2 mis-fire. I guess it's time for a tune up. Does anyone know how much they run on a avg. for a '97 with over 100k miles?

Where did you buy it from, and how much/hard was the install?

I had my father order it through worldpac... they are a parts supplier for mechanic shops so i only paid wholesale price for it. |
WHOA !!
Before you go throwing $49 or whatever at it, be sure that's the issue! Just because someone else got 'X' to fix it does NOT mean that's the same issue. P0302 is a misfire on the number 2 cylinder. The Factory repair manual lists causes as:
It does not list a faulty Ignition Coil as a possible cause - to eliminate, check Resistance between terminal 1 and 15 on the coil look for 0.3 - 0.7 Ohms @ 20 °C. One thing you do NOT want to do is remove the CoilPak and see if you can get a spark to arc to the block - this can fry the DME or CoilPak. Do these checks, then by process of elimination select the proper fix. |
