could someone help me cuz i have a check engine light that shows up running lean and another error showing high rpm...any help?

 

did u take it to autozone for the code? check your intake filter and go ahead and check the mass flow sensor and honeycomb for debris and stuff. That's pretty much all I could recommend. How many miles on your car? Maybe fuel filter?

 

what mods do you have on your car?

 

yeah i took it to auto zone for the code.. they gave me
2 for too lean
1 for too high rpms
miles on the car 64000.. engine prob has 33000. i used to have the piggy back put in it.. but i took it off. all the wires are correct i checked them 3 times. later this week ill try putting the stock intake back in cuz i have AEM cold air that i made into short ram after i drove over the water puddle and had engine changed. my rpms keep dropping from about 700 to 400 or something and going up and dropping again. even if i rav the engine and keep it at like 2000 it will drop like 300 rpms and go back up...
this sucks.. any help would be appreciated

 

bump anyone any help?
there was more problems too.. on the cold start engine would be at like 4,000 rpms for a long time and then drop. also today coming back from work the whole car was shaking like the engine was to blow up or something.
someone please help.. and i already changed to new oil and put my stock intake back in.

 

the way the idle is dipping sounds somewhat like a vacuum leak, check every single hose to be sure its not

 

i just cleaned my MAF with QD electronic cleaner... coming back from work today check engine poped again. ill take it to auto zone today and write every code that they give me. hopefuly someone here can help me. i also cleaned the throttle body with the throtlle body cleaner.

 

Could be serious issue if intake didn't have bypass valve and water is drawn into the engine.

Dealer likely to tell you to take a hike with aftermarket parts.

 

well i had the engine changed. got a used one with 28000 miles. about 33000 on the engine now. i dont get why its doing it though. all hoses are connected everything looks fine under the hood all fuses are good... then all the cables by the ECU are connected propely. the wires by ecu are just not soldered. but they were not for a long time and i didnt have this problem.

 

did you take it in to the Dealer for the reflash recall?

 

no i did not. if i fail to come up with a solution.. im taking it to the shop that put in the engine for me and hopefuly have the insurance cover it as they covered the engine and put 6 months on the engine warranty..

 

Could be a gasket?

 

gasket on what?
plus now it seems to idle fine? for now.. only when coming to a stop it goes up to like a 1000 drops to 500 and goes up to about 750 and stays.. if i rev it.. and try to keep it at certain rev lets say 1500.. it will keep dropping like 200 rpms and going back up..

 

reset your ECU and see what happens from there...

you're running out of options.

Your pump may be going bad.
Injectors might be clogged...

I dunno man...

 

i already resetted my ecu multiple times. yesterday i resetted it i guess by pulling my fuses out to check if they're good. it keeps coming back. check engine didnt come back since yesterday so i didnt go to the shop.. but if it does ill go one day this week i guess.
