Hello everyone, I have a problem with my car and wondered if it happened to you fellow j-body members. I figured this would be the best place to ask since you all probably had or heard of someone with the same issue, So, I have a 1998 Chevrolet Cavalier Z24, 5-speed with the 2.4L naturally. Im from Canada and the car has just shy of 250,000kms. Cars runs great and always has and recently a symptom has shown up. Car starts and idles normally and no codes show up from my reader AND no check engine light. The symptom is when i take off in first and any gear at low rpm when i push the gas it sputters a bit then goes away and feels normal. Anytime in any gear if i try to floor it the sputtering will show up as well. Ive been searching on line to all sorts of "Could be" problems and wanted to narrow it down. Ive heard everything from cracked spark plug to fuel filter to egr valve. So again taking off in 1st OR when i switch to any gear and rpm is low, if i push the gas even i little too hard the engine will sputter and then go away and feels normal. Its like it happens from idle to say 2-2500 rpm and then 2500 to red line the car has full power and goes no problem. I guess any posts here would be wonderful.
Thank you in advance

Sort of sounds like like a tps issue. Does your code reader allow you to read and sensor data?

I dont think so, if the TPS was the problem would i get a check engine light or would it throw a code?
thank you
Not completely true.
That's why I ask if your code reader can read sensor data.

Ill check it out
Thank you
Agreed sometimes flat spots on the tps are just too intermitent to kick a code,or check light.Checking a tps with a mulitmeter is easy if your obd reader won't.I will find my link to checking sensors and so forth and post a linked point to learning how to do this with a multimeter over the obd reader that will not.
http://www.wellsve.com/ This site has tons of info on how to check pretty much any sensor on the planet.You may have to scroll thru it and check out the diagnostics side where it takes it step by step.Hope this helps and this site has helped my tons on various things.The counter point newsletter dates back years of older material to cover items so just use it to your advantage.Good stuff and done.
