Need Help!

Ok guys I put some headers on my 98 Trans am, and now sometimes when I try to start my car it won't and I smell gas. I am pretty sure that its flooded, if I pull the fuel pump relay and crank it over it will start once it starts i put the relay back in and its fine. any info will help Thanx

did you do a tune when you put them on? with out a tune they make are cars run rich. also what plugs are you running? you dont want stock plugs go with some ngk tr55's or tr6's.

I am running tr55's and I am getting my retune soon, the code that its throwing is the Ho2s. Thanks

Now when I drive my car after sitting at a stop light then I try to go it has no power and fells like its flooded, after bout 5 seconds it opens up and goes what could this be. Had auto zone scan it and said that is a temp sensor switch and Ho2s.

i think it's in the tune. did you hook up the o2's to the frount set or the back you have to use the frount set of wires. look up a member named frost and see what he thinks.

I'm thinking the O2's are not hook up properly too. Did you use the extensions for the front O2's. You can not use the rear. These (rear O2's) are what get's deleted when you get a tune.

Also, Have you changed your fuel pump in the last 11 yrs? It may be starting to go if it is the OEM.

Mine's a 98' also with LTs and ORY and have had no issues, been running without new tune since Aug (not a DD). When I get my tax check I'll be getting my tune from Frost.

Ok will get ahold of frost and thanks guys.

Not enough here to do anything but speculate... an air leak in the exhaust before or near the O2s, bad O2s, bad extensions, etc.

Think maybe its just to lean.

it sounds fat to me not lean if that is the case that is a bad thing and you will burn up pistons long tubes make are cars run fat most of the time.

**0verkill** · 01-03-2010, 09:15 AM

No; that's just not how it works. Air leaks fool the O2s into thinking a lean condition exists and the car overfuels itself because it is somewhat stupid in this department.

Yeah this is deffinetly an issue with an air leak or bad/ bad connection to O/2 sensors.

Installing LT's on a stock engine with stock plugs is not going to magically make it not run right unless one of the above has happened. A tune will make it run better/right but it should run!
