07 vibe with hicups

[et907a]

i have an 07 vibe its automatic with just 4500 miles it was hit before i bought it and i dont think the dealer would warranty the car.it has no code showing but feels like i loose a cylinder sometimes when driving at a steady speed idles great, plugs(orginal) look black like it is runing rich thanks

I need some more info from you.Does it feel like it drops a cylinder when it's cold or warm to hot only.Is it one plug that's all fouled up or all of them?And when you step on the gas,do you notice any black or white smoke coming out of the exhaust.

i have only felt it hot all the plugs looked like black soot .i only see white smoke when i start.when i first got it the intake was cracked and on 2 cylinders the electrode was closed causing a code i regapped and it ran fine i have also spray the map sensor thanks do think i should change plugs

[kevera]

I would change the plugs.To be honest,something sounds off,are you sure the engine has only 4500 miles on it.Maybe the engine was replaced with an older one due to the accident or for some other reason.

[et907a]

definitely orginal motor i put 2500 miles on it what plugs would you suggest what about air filter thanks

OEM Denso Iridium or NGK IX Iridium. It shouldn't need a new air filter yet but an OEM Denso would be good when the time comes.

I dont think hit should be an issue. I bought mine used with 23000 on it, took it to the dealer and they said I had warrantee left. At least ask them 1st before changing anything.

changed plugs and air filter spoke to dealer he wanted me to authorize for 2 hrs to determine what was wrong in case problem was related to accident. car finaly thru a code 301.01 and 301.02 along with a noise from the engine that sounded like a lifter or could an injecter make a similar noise.i just sorry i cleared the code any ideas thanks elliot

301 and 302 are misfire codes, cylinder 1 and 2. Take it to where you bought it and get it checked. I'd say it's injectors partly blocked but the mileage is very low for any kind of problem. You could throw a lot of parts at it before you find the problem. Try running a tank or two of Techron, it worked for me when I had a misfire.
