Car problem still

Did you check for a vacuum leak?

How do u do that auto zone said it could be a gas cap the engine light came on again and still running sluggish up hill and at stops but they tested it and said codes were historic don’t now how to reset already did the battery

Someone said it could be in limp mode what is that and how do I fix her

To check for vacuum leak, have engine running at idle and spray brake cleaner around intake manifold and any vacuum source, if engine has a leak, idle will raise,lower,or engine will die. let me know how it goes.

It doesn’t have leaks that I see if it’s in limp mode how do I get it out of it it still does it on hills and at stops and engine light back on I just got this after it’s sitting for 5yrs and they said nothing wrong I have to smog it I need to have it working

How can I get the old codes off and reset her

you can't see a vacuum leak.

Well just tested it up hill and still hesitants god only 45 up hill and if it’s in limp mode how do I get it out so it won’t do this

It still hesitants going up hill doesn’t want to speed up to go up hill what else can be wrong can it be in limp mode like auto zone said and if so how do I get her out of it I unplugged the battery already and still has engine light on

Check and feel how much exhaust is coming out the tail pipe,wondering if your exhaust is clogged. if that code you had was for a converter issue it could of broke apart and clogged exhaust.

I had her tested again by auto zone and these are the codes that came up Po404, po108, po131, po300, po404,po452, po463, p1106 what does this all mean and how much would it cost to get her fixed I use her to travel to work up hill and around 150 miles everyday
