Pa1s/c

My car recently started to feel like the clutch was slippin but a further look and it wasnt the clutch... i shut it off at my house and turned it back on and it had a hard time running the rmps kept moving from really low to really high and the engine light came on im having a buddy come over to map it and see whats wrong but does anyone have an idea of what it could be...

Dirty throttle body? IT's hard to tell without more information. I have heard that our throttle bodies get gunked up from the crankcase vent, and when they do it causes the RPMs to rise and fall.

take out headlight remover maf spray down with maf cleaner
take intake off disconnect lines to throttle body, unbolt, clean and wipe down with throttle body cleaner

if the code is p0171 it is because of the intake and you are fine so find out what the code is

If the throttle is REALLY gumed up, you could have a engine light for TPS (THrottle POsition Sensor) or something similar. INjen intake could cause a light too.

but why wouldn't the engine light come on before i know its been on for a while

you mean p0171 like i said that is from the intake just clean the throttle body and maf and you should be fine maybe run some fuel cleaner through it

Clean the throttle plate BY HAND let me make sure you understand this before you get spray can happy and end up buying a new TB. Soak a rag, manually open the throttle with your finger (it'll open and it won't hurt anything) and wipe the contact areas where blade meets body until it's clean the rest isn't particularly important. Oh and they make a MAF/ Electronics SPECIFIC spray cleaner...use that please, residue from other chems will skew readings.

okay we hooked up the obd2 and we cleared the message for the intake and that shut off the engine light.. but the second message said that the car was running to lean we just let it idle out and cleared it... runs perfect and shifts smooth... i dunno maybe it was just a little hiccup in the system thanks for all the tips and help with though i still plan to tear that stuff down and clean it just to be safe
