1990pathy

my pathy is doing this thing only when its cold (first start up or start it then just go) it will putter out and die.. it will start right back up and be fine after that. but i was thinking it was the temp sensor for the ecu havnt tried anything yet but i did give it a tune up and it runs alot better but still dies

any ideas guys

Failure mode???? What's that mean.

So when I pull the plugs and if there is a wet black one that looks like its not right how would I fix it ??? New fuel injector seals?

Ok so it threw two codes 33 heated oxygen sensor and 45 fuel injector leak!!! Anyone know how to look for a leak. I don't smell has and there's no wet spots where the fuel injectors are

Ya I did it a while ago but there was nothing throwing a code but I'll try it again tomorrow too see if it's saying something different

So my pathy has an issue where it likes to bogg out only when cold or at first start up when I start to take off. It will back fire(once and a while) and just have no power. Where would I start. I know it's not the Maf wire. That's good. I do notice when I will be on the freeway my check engine lite will flicker on. When I let off the gas it goes away(this is another thing wrong) then when back on throttle the light comes on. Tps sensor bad maybe. I just don't know. Fuel pump going out !!! Thank you in advance for any help. I'm not on here much

No codes.. But the check engine light comes on all the time??? No clue why.

Hey guys. So my pathy has been doing a weird thing where it will just die out of the blue... anyone had this problem before????? It will start right back up but ihave no clue where to start to diagnose this problem???

Ya I'm going to fix it tomorrow.thanks for the important info

yes the alty is brand new...well a year old or so maybe i should go get it checked out thanks

So I have a 90 pathy. And for the last few months it's been doing this weird thing where the volt meter will fluctuate from 12 to 15v or so and all the dash lights will freak out. the trans light brake light and the power at switch will start flashing in sequence with the voltmeter!!!! I have no our where to start. It doesn't effect how it drives it just freaks me out cause I don't want something to catch fire or melt. What could it be... Posted from my iPhone!!!!

Sweet. Thanks for the info. I'll get to lookin

No skid plate... But I have gap guards. I think it comes from the bottom up!!

So when I take my rig mudding, I notice when I go thru big puddles of mud and water. The alternator will drop to about 10 volts. Is there a way to get a cover or something to prevent it from getting wet?
