Having some engine trouble.

[Jordan]

Yeah, one of the mechanics suggested to check the TPS for oil. That seems very likely, as it likes to pool there.

[KenC]

check the TPS

Just make sure that you use a coversheet. :D

JK, man. I hope you get this figured out before Sunday!

[Fred]

Fred, I can pull to 6940 without any problems at part throttle. (posting from work)

Check the AFM or TPS.

[blunttech]

clean the electrical connection at the afm

Someone else has this problem also :x . I have had this problem for a year now. It started out as a random cutting out around 6000rpm and then it gradually got worse until it wouldn't go past 6000 at WOT. At partial throttle it will go all the way to redline.
I have replaced the following since then and haven't fixed it.
-New TPS
-Tested CPS
-Plugs
-wires
-distributer cap
-rotor
-tried a different ECU
-fuel filter
-octane booster

None of these fixed the problem. I am thinking now it might be that damn sensor below the throttle body.

Need to find the culprit before this weekend meet or I won't be going.

My ass you're not going... :evil:

I don't care if I have to smack your silly ass upside the head with a 2 x 4 and throw you in my trunk.

[Jordan]

AFM is completely spotless inside and out. Havent tested it yet.

TPS was well oiled, but tested OK. I cleaned it, and it tested OK again.

No signs of any air leaks or anything of that sort.

I cleaned all the connectors to the AFM, and TPS. The TPS one being wet with oil.

I will remove all the spark plugs, clean them, reinstall, reassemble the engine.. and try again.

[diegom6]

I dunno, but maybe check you fuel hose in tank pump if you are runing an aftermarket one.

I had a problem with the hose and was doing cut off's, but oh well seems is not you r problem.

Maybe your coil? Cap? or maybe the Chip?

[Jordan]

I have a spare coil, so I am going to switch that out as well if what I've done tonight solves nothing.

I took the spark plugs out, all of them look to be good, working well in there heat range and all that jazz... but what do I know.

Jordan, to be honest, I know I don't have nearly the technical expertise as you, but it sounds to me like an ECU / chip problem. If it is in fact just plain cutting out at 6k, that's at least what it sounds like to me. I could be and probably are totally off, though.

I hope you get it fixed.

[Mystikal]

Get a stock chip.

[jgentile]

im with everyone else, put in a stock chip and see what happens

[Nick325is]

Its not ECU. This sounds like the exact same problem I have. It started out doing it on occasion and then got so it did it all the time. I swapped out the ECU and reset it and no dice.


Nick

[Jordan]

I don't have a stock chip available to use.

[Jordan]

So I tested and cleaned the TPS.
Checked the AFM, looks fine.
Looked for air leaks, and probed for leaks with propane. No leaks found.
Removed, checked, and cleaned spark plugs.

Problem unchanged. :(
