I bought my second first gen 2.5 TL Friday. I have an appointment at the dealership in a few hours for an inspection for it. A problem I'm running into is that once the car warms up, it takes FOREVER to accelerate. Like I can see Christmas passing me on the interstate. Then when I put my foot on the gas it'll slowly accelerate more then sometimes I'll feel the car jerk forward like I floored it for a couple seconds then it will go back down to its original speed. Then sometimes when I'm just holding my foot steady or the cruise control is on, the car decelerates by itself then it'll slowly go back up and then jerk forward some more. It's kind of embarrassing. I got the error code P1298 at autozone and it said it was the ELD high output and/or low output. It also has a misfire on cyl 1 and 4. Anyone has the similar problem of Christmas passing them?

check your tailpipe when you first start it and then again when its warm, its maybe a long shot but it sounds like it could be another catalytic converter issue....BUT that 1298 output code is related to the transmission right? that kinda seems like a possibility...:/

'ELD' stands for electronic load detector. It's should be located in the under hood fuse box. I say 'should be' because I've never had to deal with that on my Acura but I did come across that code on my sister in law's 2001 Civic and that's what fixed it. It looks like a large squarish relay.

EDIT to my previous post. Come to find out that the first gen TL doesn't have an ELD per se. The ELD circuit is part of the fuse box. Either the entire fuse box would need to be replaced or the ELD circuit would need to be bypassed if cleaning the connections and grounds doesn't solve the problem. I've read a couple of posts on Honda sites and one on this site but nothing that is clearly specific for the TL. Here's one with a diagram but it's for a Honda. According to the poster it will work on all Acura/Honda 1997-2002.

The acura dealership said that the distributor is broken and that is what is causing it and there was something else but they dont repair engines so I'll just replace the fuse box myself here for $65 (ebay or amazon) and they said there was an incorrect gear ratio so I will buy a transmission rebuild kit because I have a second car to hold me over but no money for a shop to rebuild it so I'll do it myself. I'm going to try spark plugs for the misfires first and start with the cheap stuff.

HP11

These cars don't have a distributor. They're individual coil on plug crank triggered ignition. Don't understand what you mean by 'incorrect gear ratio'.

mikeysinoda

I do remember reading that somewhere on here and also somewhere else. I forgot that this morning when I was there. I'll just replace the fuse box and spark plugs and see if that fixes everything. Would you happen to know what the individual coil thing does?

HP11

All I meant is that they have 6 ignition coils; 1 per cylinder on the 3.2 or in your case, 5 ignition coils; 1 per cylinder on the 2.5. If you have a misfire on 1 and 4, move those coils to other cylinders; say 2 and 5 and see if the misfire follows them. If is does, the coils would be the problem.

Ok

jrot

well it sounds like your trans has packed up, and the car cannot compensate any further and thats whats causing the other codes....i doubt the entire fuse box is bad but its not impossible...still though check the tailpipe like i said just to be sure. ive seen crappy cats do all sorts of fun stuff and it seems like a few of us have dealt with it lately. my car did exactly what yours is doing though only on long road trips and the cat fixed mine....its worth checking....

G25A have a distributor.

Jrot...white smoke comes out of the tailpipe. Not a lot but more than should.

mikeysinoda

wait u said when i start it and when it warms up. i'm gonna do that real quick

mikeysinoda

Ok. It is fine when I first start it. But when it warms up, white smoke comes out.

mikeysinoda

When it is idling, the rpms vary. i revved the engine to 3000 rpms and when it dipped down, it went too low and died.

check your idle control valve on the throttle body... i wonder if it is all gunked up... i can't remember but does the 2.5 have a MAF sensor on the intake?

jrot

i dont think i would worry bout the white smoke at this point i dont know what part of the world your in but its not uncommon this time of year, most people never know it. when i say check the tail pipe i meant more for air pressure. if the cat was to clog at warmed up temp do to expansion then you would have proper flow at cold and little to know flow at warmed up...

now im curious though, does the problem present itself only in drive or do you notice it when its in park as well?

mikeysinoda

It idles bad in park and when im stopped at a light in drive. The acceleration problem tends to only occur after the car is warmed up. I read that the ignition coil that is by the passenger side fender could also cause the tranny problem. It doesnt shift until it gets to 4.5k rpms and acceleration is very slow. I called a trans shop and asked about a rebuild and he asked the symptoms and he said he's never had this generation acura come in his shop with it doing that without it being something electrical and that if it was the tranny then i'd feel it slipping or it just wouldnt work at all. I will check air flow

mikeysinoda

I checked it. It didn't have much airflow and I didn't notice any difference in the air flow between cold and warm. I compared it to an 03 Ford Taurus I have also and the taurus had a lot more air flow than the acura but the acura also has 2 pipes on the end of the muffler vs the Taurus' 1.

mikeysinoda

Fixed it! It was the ignition coil.

main70072

Cool! If you don't mind me asking, how much did it cost you?

HP11

MY BAD! All my posts were based on the assumption that the 2.5 was also coil on plug. I imagine that the coil would still be expensive to buy new, a 3.2 coil ranges from 80 bucks or so at the auto parts stores to 150 at the dealer. At least you don't have to deal with 6 of them!

mikeysinoda

Ikr! I paid $79.xx at Autozone and it took all of maybe 5-10 minutes to change only because I had to break the bolts free.

mikeysinoda

I will have to find that and clean that because it appears to have been sitting a while before I bought it due to the cobwebs and dirt under the hood so it probably is gunked up pretty good.

mikeysinoda

Yes it has the MAF

HP11

After replacing the coil on a couple of family members's Hondas, I recall that Honda/Acura coils are kind of pricey, no matter how many coils the car has! Imagine replacing all 6 on a 3.2 at dealer price; you'd be right at $1000 with tax.

jrot

my cars not even worth that much hahaha....

mikeysinoda

Lol. I thought it fixed it but it does show a great amount of improvement. I'm replacing the spark plug seals due to oil in the holes around the plugs and since I'm going to have it apart, I'm replacing the valve cover gasket too. Hopefully the fusebox with the new ELD will fix it the rest of the way. Luckily all of the parts so far have been under $50 except the ignition coil.
