The weird part about today I install the 02 reader today this morning it's 6:44 new Orleans now and it says no faulty codes and the lights off but why does it come back on two days again don't understand?? Then I all ready bought new upstream cat converter flange to see if that might work think I should just install new flange and you might be right if somebody else took my car for Joy ride hit something underneath car might be a leak somewhere but we're to first look I thought about upstream converter flange first to change because codes are reading bank 1 so .what you think I should do? Need help thank you so much reading all this information might help someone on here with same problem I have

Just let you know the car stop misfire but light stays on, but now looks find since I keep delete the fault codes on the odb2 .let's see if it hold till Monday I get back with you to see what next I should do thanks for your support you been good help

What I'm saying is every time I foll around the manifold changing spark plugs or anything like that that dam light comes on do you think it could me something electrical short power something weird do my part but the lights off it's usually come back the car engine light 2 days this 3rd let's see if come back on fully day today today or till Monday 😁 if you don't hear from me Monday it's because light still stands off

 

[wendyfelixalegria]

O buy the way I forgot to tell you soon I do a regular scan on the car computer it says no fault codes no more weird huh?? I wonder y does that ??

 

[wendyfelixalegria]

Have a nother question in the procedure a change in the car boots and spark plug is any reason I have to clean the manifold in the inside when I put it back cuz it was kind of oily not that much do spark plugs too the old ones I mean to say

Car runs great do now shift gears like it's new because I changed the transmission fluid when it hit 100,000 MI filter everything when I bought it from the dealership it only had 50 thousand miles on it

 

[wendyfelixalegria]

Clean the transmission magnets pan very good too everything the two filter small in the pan filter those transmission are very delicate put the original transmission fluid back in ..buy y sometimes when car gets hot to it's temperature when I'm in park to put on drive it gets a little hard to put on drive not that much do but I can hear it thump outside soon change gears this happens a few times not a lot do you think something is going out I lose both or something

 

[wendyfelixalegria]

Maybe I have to judge something in the transmission??

 

[wendyfelixalegria]

Adjust I mean

 

[wendyfelixalegria]

No I don't have to bring it tol a inspection
