Can someone give me a check list of areas to check to get rid of this hesitation I have when accelerating? It's very short in duration and only occurs when I am accelerating hard. to help narrow down some items it has a new timing belt, clutch, oil, oil filter, pcv, drive belts nd a new spk plug in cyl #1 due to the check engine light that keeps coming on stating EGR and cyl # 1 misfire. Oh i almost for got it's a 1997 Neon 2.0 SOHC 5-speed MTX sedan. Thanks!

 

O2 sensors

 

thanks! question though wouldn't me C.E.L. light come with that problem?

 

sometimes

 

Wow, the first thing a mechanic recommends is stretchedTiming Belt or Timing Chain for a vehicle with hesitation not 02 sensors.

 

Well he just said "it has a new timing belt" so i doubt its a timing issue. Just inscase you dont know, the failure symptoms for an O2 sensorwould be decreased fuel economy, hesitation on acceleration, stalling, surging, rough idle and increased tailpipe emissions. Maybe you should tell your mechanic that before he charges you alot of money for a non issue.

Even if the timing belt had streched he would feel hesitation during all operating conditions not just during accel

 

Thanks for the info 12 Volt. 1 more for you I hear a rattling sound at idle and between shifts. I knnow it's not the engine it sounds more like a loose heat shield near the exhaust. Someone said it could be a bad CAT. Your views???????

 

my sister had(honda civic) that bad rattling sound too, turned out the heat sheild on her cat was missing a screw. Just get under the car and see if you have a loose heat sheild somewhere.

The best way to determine if the catalytic converter has failed is by testing the exhaust with testing procedures like those used in state and local inspection programs. However, the following symptoms may also indicate a need for converter replacement:
[ul][*]Broken or rusted out converter body or end tubes.[*]Bits of substrate in other sections of the exhaust system.[*]No rattle in a pellitized converter (If the converter doesn't rattle, the pellets may have melted together or fallen out.[*]A rattle in a monolithic converter (A rattle in this kind of converter indicates the substrate has separated.) [/ul]

as always thanks a bunch. hey i sent another post requesting info on exhaust and intake components, can you check it out for me?
