engine problem diagnosis, please...

[nuclearmuscle523]

It sounds a little like an issue with the timing chain. It wouldn't throw a code if say, the tensioner was wacked up. Issues with valve components can hide from the computer also. If it was a stuck valve I'm pretty sure a code will throw.

same thing my dad told me...probably a timing chain issue.

do a 5.0 swap, and see if that works.

lol, i'll just go pluck off money from my money tree.

Have you thought about your tps, or maf? I would definitely try compression test just to be safe. The thing with sensors is as long as sensors are within their parameters they will not throw a code, so they can still make a car run shitty without a code.

i couldnt drive it anyways and had to get back to houston. my dad is gonna tow my car to his mechanic friend out there and have him do a compression test and possibly pull the head and check it out.

Where are you at with this?Any luck fixing it?

Can I get some of those seeds?

Mine was very similar when my tps went bad. Very rich and lopey. Also wouldent stay running.

did you have a check engine light? I have been suspicious of that damn throttle body since back in 06 when everybody was having problems with them.

Still working on getting it towed to houston. I already have a new motor lined up and the swap out at my tuner. However, before I got through with this, I'm gonna swap out throttle bodys and see if that helps.

Are you buying Gregs motor?I saw he looked you up on the WTB ads.

 

[tyler_2118]

No light for a long time until the sensor went out completely

Try a new tps if the throttle body swap does not work

I am talking to him about it right now, however, we are trying to get our timing down first. He may be pulling that motor out later than I will be needing to get one.

Ok, I'll definately check that out.

I will, any idea on how much a new one costs (off the top of your head).

Also, let me ask you. If the TPS or the throttle body went bad, would that cause one of my heads to smoke? It's not a lot of smoke like what comes out of the exhaust, but it is white smoke coming out the drivers side valve cover.

 

[tyler_2118]

I cant remember how much they cost but there not that bad, I dont know about the smoke thing? I wouldn't thinks so but from starting and dying and over again who knows.

Is there a voltage test I can do to test the TPS?

 

[tyler_2118]

Ya I think I read in here some were u can but I have no Clue how. try to borrow a tps to see if that's the problem.
